Friend #1: dude! i saw your mom last night! she was hot!
Friend #2: your best friend's sister!
Friend #!: you have a sister!?

dude: what happened last night!?
dude 2: your best friend's sister!

your man 

Your man is a piece of Irish slang which refers to someone that you are somehow connected with but don't personally know. Its general tone is derogatory but it's not offensive.

Synonymous with the Australian "old mate."

If you saw a drunk person stumbling across the road you could say..."have a look at your man over there" or in a traffic incident....."and your man just drove straight into me".

Your arse 

One of those ultimate comebacks, like your mum and your face. Not as commonly used.

A: This smells
B: Your arse!

1: Move outta the way!
2: Your mum!
1: Ya what?
2: Your face!
1: What the hell?
2: YOUR ARSE!

- A situation that actually happened to one of my friends.

Your Mom Goes to College 

The most retarded insult ever, said by the character Kip in the movie Napoleon Dynamite(2004).

Deb: "Is there anyone else here? I'm trying to earn money for college."
Kip: (In the background) "Your mom goes to college!"
