Hi Cho Yoon JI In the context of the sentence (coming home from the pub) in British English it's an impolite slang word meaning 'drunk' or 'intoxicated' through drinking too much alcohol. You are correct, in American English it can also mean 'very annoyed', but it is unlikely in this instance.

Well, it's certainly not used that way in american english. 'pissed' for drunk is strictly UK, Australia... what do you call that if it's not British?

Pissed = very drunk. This sentence may be written "they are coming home very drunk from the pub" Pub is the shortened form of "public house" and is similar to a beer keller or bar. Don't the word 'pissed' in polite company you will be considered vulgar. Don't describe English as "British English" this is incorrect.

"Pissed" means drunk. "Pissed off" means annoyed. They are used a lot in British English, so it's important to know the difference! Also remember these phrases are very casual, and shouldn't be used in any formal or polite situations.
