your mom 

Possibly the most idiotic, uncreative insult ever. It's similar to a "yo mama joke", but a your mom joke is even more retarded. It's usually used by morons and idiots who can't come up with a decent comeback or insult. Another annoying thing is when a dumbass says a "your mom" insult, another dumbass (often a random douchebag that has nothing to do with the situation, but decides to butt in) will say something like "OHHHHHHHH!!!" or "You just got burned!!!".

(guy 1 pushes guy 2)
guy 2: What the Hell you, pushed me you motherfucking, piece of shit, cock sucking, ass-faced, douchebag!
guy 1: Well ummmm, I pushed your mom if you know what I mean!
random idiot: OHHHHHHH!!! You got burned!!!
guy 2: That was a shitty comeback
guy 1: Your mom is a shitty comeback!
random idiot: OHHHHHHHH!!! Burned again!!!
(guy 2 kicks the shit out of guy 1 and random idiot for being annoying and retarded)

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*
