I didn't mean to swear words,like shxt or fxxk.Haha
Colloquialisms and slang change a lot as time goes on! They also change a lot depending on where you are, as David said.
I could help you with it, if you like!
To refer to David's comment as an example, the word "Cool" is often considered slang for "I liked that!"
If you have any particular ones you would like to highlight for me, please send me a message! :)
There are so many it is hard to say as every English speaking nation/county/city/village will have different slang.
For example, what used to be 'cool' then became 'epic' and I am sure that has changed again now.
