your mom 

something you say when you can't think of anything else to say, or if you just want to insult someone without thinking too hard. Can also be varied in response.

guy #1 - "Dude, shut up"
guy #2 - "yeah well, your mom!"
guy #1 - "well uh, <i>your</i> mom!"
guy #2 - "yeah well, your mom's daughter's mom!"
guy #1 - "your mom's mom's mom's grandson's son's mom!"
guy #2 - "your sister!"
guy #1 - "YOU BASTARD!!" *he hits guy #2 with a fantastic right hook*

A great response that can be used in 99% of argumentative situations.

John: Fuck you
Me: I fucked your mom

John: Your a dick
Me: Your mom doesn't mind

John: Get off my nuts dude
Me: I'm just getting you back because your mom wouldn't get off mine.

John: I'm gonna beat your ass dude.
Me: Just like I beat your mom's pussy?

Your Mom 

The last desperate resort to save what's left of your saggy public image, in an obviously lost verbal or written argument.

"Your a fat pig who likes to masterbate in his own sweat, i even caught you masterbating, you cant deny it anymore."
-"Yeah your mom."
