An insult given typically when one has been defeated in an argument but does not want to admit it. People who give this insult may also lack wit and originality, or simply may be obnoxious. It spun off of the largely popular yo mamma jokes.
Person A: You see, you're popular because you developed early and started giving handjobs when you were twelve and now you can't stand to look at yourself in the mirror because all you see is a whore. So you pick on Meg to avoid the inevitable realization that once your body is used up by age 19 you're going to be a worn out, chalky skinned burlap sack that even your step dad won't want. How's that? Am I in the ballpark?
Person B: Yeah, well... your mom.
Person B: Yeah, well... your mom.
