During an argument, one can use Your Mom! to turn the tide in his/her favor. Used only when you know that you can't possibly win the fight with an actual reply. Also note that your oppenent can cancel Your Mom by repeating it after you.
Todd:...And that's why I'm right, Chris.
Chris: Yeah...but...your mom! Oh! It's on!
Todd: Oh yeah? Your mom too! Burn!
Chris: What? No, you can't do that! NOOOO!
Chris: Yeah...but...your mom! Oh! It's on!
Todd: Oh yeah? Your mom too! Burn!
Chris: What? No, you can't do that! NOOOO!

A completely stupid thing to say when someone is pissed off or has just been burned, but can't think of anything better.

A phrase most often used by wiggers/wangstas and people in chatrooms. It is only used as the last desperate attempt to win an argument, although it really doesn't have any meaning whatsoever.
Wangsta 1: I hate your ass!
Wangsta 2: You're a stupid piece of shit!
Wangsta 1: Shut up jackass!
Wangsta 2: Your Mom!
Wangsta 2: You're a stupid piece of shit!
Wangsta 1: Shut up jackass!
Wangsta 2: Your Mom!
