40 Most Memorable British Slang Words for ESL Learners

Key takeaways

• British slang is partly regional: some words are used across the whole UK (mate, cheers, brilliant), others are specifically London (innit, bare), Northern English (nowt), or Scottish (braw, dreich). Knowing which is which helps with context.
• Register matters. Many British slang words are fine with colleagues and friends but wrong in a formal setting. Bloke and cheeky are fine at a company lunch; they are the wrong register for a job interview.
• The single most versatile word in British informal English is cheers: it functions as thank you, goodbye, and a toast at the same time, depending on context.
• The 40 words below fall into five groups: everyday reactions, people, feelings and states, things and situations, and informal actions.

ESL learners often reach a point where their English is grammatically strong but British TV, friends, or colleagues leave them guessing. The reason is usually informal vocabulary. A character says I’m absolutely knackered and the learner knows every word in that sentence except the key one.

British slang fills a gap that no coursebook covers.

This guide covers 40 British slang words grouped into five themes: everyday reactions, describing people, expressing feelings, things and situations, and informal actions. Each entry includes the definition, a natural example sentence, and notes on register or regional use where they matter.

Slang is learned by exposure, not by reading lists. Find a private English tutor through italki, which has connected over 10 million learners with native-speaking teachers since 2007, and practice these words in actual informal conversation where you can hear whether the tone is landing right.

Everyday reactions and affirmations

Word	Meaning	Example
Cheers	thank you / goodbye / a toast	Cheers for the help. / Cheers, see you tomorrow.
Brilliant	excellent, great	That’s brilliant news.
Lovely	nice, pleasant (can be ironic)	Lovely to meet you.
Ace	excellent, fantastic	That film was ace.
Sorted	arranged, fixed, dealt with	All confirmed, we’re sorted.
Blimey	exclamation of surprise	Blimey, that was expensive.
Crikey	milder exclamation of surprise	Crikey, I didn’t expect that.
Innit	isn’t it? / right? (London/informal)	That was good, innit.

Cheers deserves special attention because it does so much. In a shop, it means thank you. In a conversation ending, it means goodbye. Over a drink, it’s the toast. Getting the tone wrong for any of these is almost impossible because context makes the meaning clear.

Sorted is particularly useful because it covers a wide range of resolutions: a problem is sorted, a plan is sorted, a booking is sorted. It’s a shortcut that replaces “it’s been taken care of.”

People

Word	Meaning	Example
Mate	friend, pal (also used with strangers)	Thanks, mate. / Alright mate?
Bloke	man, guy	He’s a nice bloke.
Lad	young man, often with a sense of camaraderie	He’s one of the lads.
Lass	young woman (Northern English, Scottish)	She’s a lovely lass.
Posh	upper-class, fancy, expensive-sounding	That restaurant is very posh.
Cheeky	boldly playful, mildly disrespectful in a charming way	Don’t be cheeky. / A cheeky request.
Dodgy	suspicious, unreliable, questionable	That deal sounds dodgy. / A dodgy area.
Gobby	loud, outspoken, often in a negative sense	She was a bit gobby in the meeting.

Mate is used in British English to address strangers, colleagues, and close friends alike. The tone of voice distinguishes friendly from sarcastic. An angry mate means the opposite of friendship.

Dodgy is one of the most useful British slang words because it applies to people, situations, goods, and plans equally. A dodgy bloke, a dodgy deal, a dodgy kebab: the core meaning is always “something that seems wrong or risky.”

Feelings and states

Word	Meaning	Example
Chuffed	very pleased, proud	I’m dead chuffed about the promotion.
Gutted	very disappointed, devastated	I’m absolutely gutted we lost.
Knackered	exhausted	I’m knackered, I need to sleep.
Skint	broke, having no money	I can’t come out, I’m skint this week.
Buzzing	excited, full of energy	She’s absolutely buzzing after the news.
Peckish	slightly hungry	I’m a bit peckish, got any biscuits?
Miffed	slightly annoyed	He was a bit miffed about not being invited.
Narked	irritated, annoyed (stronger than miffed)	She looked narked when she found out.

Chuffed and gutted are exact emotional opposites and both intensify with absolutely or dead: absolutely chuffed, dead gutted. Knowing both is useful for any conversation about results, news, or outcomes.

Knackered is among the most commonly heard slang words in British English and appears across all age groups and regions. It always means exhausted, never anything else.

An English language tutor can help you calibrate when these words fit and when they are too informal, which is as important as knowing the definitions. italki has 30,000+ teachers across 150+ languages, including qualified British English teachers who use authentic conversation to build register awareness alongside vocabulary.

Things and situations

Word	Meaning	Example
Banter	playful, witty exchange or teasing between friends	The banter was great. / Just having a bit of banter.
Faff	unnecessary fussing, wasted time or effort	Stop faffing and just decide. / All that faff for nothing.
Quid	British pound (informal, always singular for amounts)	It cost me twenty quid.
Rubbish	nonsense, terrible, or literally garbage	That idea is rubbish. / Throw it in the rubbish.
Kerfuffle	a commotion or fuss over something minor	There was a bit of a kerfuffle at the airport.
Waffle	to talk at length without saying much	He just waffled for ten minutes.
Bodge	to fix or make something badly or with poor materials	Someone bodged the repair, it leaked again.
Daft	silly, foolish (affectionate or mildly critical)	Don’t be daft, of course you can come.

Banter is a cultural concept in British English as much as it is a word. It refers to friendly teasing and wit, and being described as “good at banter” is a genuine compliment. Taking banter too seriously is itself considered a social error in informal British settings.

Faff is both a noun and a verb. What a faff (what a waste of time/effort) and stop faffing (stop wasting time) are both common.

Informal actions and expressions

Word/Expression	Meaning	Example
Take the mickey (out of)	to tease or mock someone	Are you taking the mickey?
Have a moan	to complain	She always has a moan about the commute.
Wind up	to tease someone or to end up in a situation	He wound me up. / We wound up at a pub.
Leg it	to run away quickly	When the alarm went off, they legged it.
Suss out	to figure out or investigate	Can you suss out what’s going on?
Chat up	to flirt with someone	He spent the evening chatting her up.
Nicked	stolen, or arrested (past tense of nick)	Someone nicked my phone. / He got nicked.
Bob’s your uncle	and there you have it, it’s that simple	Add the code, press enter, and bob’s your uncle.

Bob’s your uncle has no clear etymology that everyone agrees on, but its meaning is consistent: it’s used to close a simple set of instructions, meaning “and that’s all there is to it.” It is very British, very informal, and worth knowing if you interact with British speakers regularly.

Wind up is a good example of how a single phrasal verb can mean two different things: to tease someone (always intentional) and to end up somewhere (always the result of circumstances). Context makes the meaning clear.

Getting the tone right

Knowing a slang word and knowing when it fits are different skills. Register, relationship, and setting all determine whether mate lands as friendly or aggressive, whether rubbish sounds casual or dismissive, and whether cheeky reads as charming or rude. The only way to calibrate that is through real informal conversation with someone who hears British English every day.

FAQ

Is British slang the same across the UK?

No. Some words are used across England, Scotland, Wales, and Northern Ireland (mate, cheers, brilliant). Others are regional: braw (great, fine) is Scottish; nowt (nothing) is Northern English; tidy (great, fine) is Welsh slang. London has its own distinct slang, partly influenced by Cockney rhyming slang and multi-cultural London English.

Can I use these words with British colleagues at work?

Some are fine in most professional settings (sorted, brilliant, mate between colleagues). Others (skint, knackered, bodge) are informal and belong more in social conversation. Gobby, narked, and take the mickey are best reserved for contexts where you know the other person well.

What is Cockney rhyming slang?

A form of British slang originating in East London where a phrase that rhymes with a word replaces the word itself. Stairs becomes apples and pears. Phone becomes dog and bone. Feet becomes plates of meat. Cockney rhyming slang appears in British media and culture but is less commonly used in everyday speech now, except in certain communities and among older speakers.

What does “having a laugh” mean in British English?

It has two meanings, both common. The first is literal: we were having a laugh means we were joking or having fun. The second is sarcastic: You’re having a laugh (or you must be having a laugh) means “you can’t be serious.” Context makes the meaning clear.
