Answer 1

a piece of cake = when something is too easy you say it's a piece of cake. this subject is a piece of cake, I'm going to rock the test!
come on = come on, dude. let's go out tonight?!
really? = did your dog eat your homework? really?
take care = you use in the end of a conversation like we use here in Brazil (se cuida) take care, bye!
are you done? = are you done with the hairdryer? if someone was using something and you're asking if they finished. or in a argument - are you done, Jessica? (já acabou Jéssica? kkk)
i'm almost done = david are you done with the red pen? no, I almost done! just finishing my paper.
I'm not done yet= same as the other example, but this one you don't know when you will finish, you just didn't finish. the other one you know that you're almost finishing.
I'm done= I can't argue with you anymore, I'm done!
I'm done with this class, I just hate it.
it's done = Maria have you finished the report? yes, it's done!
that's shame = you can't spread lies about everyone, that's shame! shame on you.
I didn't mean to do it = I'm sorry I broke your lamp! I didn't mean to do it, it's as an accident.
it was not my fault = it's was not my fault that the lamp broke, the cat did it.
I was just joking/kidding = don't take me too serious, I was just joking.
are you potty mouth? = watch your words! are you a potty mouth?
