your mom 

A phrase employed as a last ditch effort to save yourself in an arguement, avoid work, insult someone or simply when you have nothing else better to say.

Alex, did you do the rest of our very important project that's due today?

Errr..

You DIDN'T do it?! I can't believe how irisponsible you are!

I didn't do the project, but I did do your mom.

your mom 

A really lame comeback for when people can't think of anything else. Used mostly by high school kids or adults trying to be cool with the "younger crowd". Usually followed by "OHHHHHHHH" and/or "BURRRRRRRRRRN". Gets really annoying really really fast.

Kid: You just won't play dodgeball against us 'cause you know you'll LOSE!
Teacher: Hey...hey...YOUR MOM!
Class: OHHHHHHHHHHH!!! BURN!!! *laughs like idiots*
