A typical childish insult from teenagers 11-16. Sometimes, because they've got nothing else to say, or because they think it makes them look 'big'
E.G. 1:

Jenny: *Yawn*

Shane: You tired?

Jenny: Yeah.. a bit.

Shane: Well your mum wasn't tired in bed last night!

E.G. 2:

Jenny: You're so childish!

Shane: No I'm not, you motherfucking whore.

Jenny: Prove it then, cuntfaced frog featured toadostical moronized mong penguin tatoo moose!!!!

Shane: ...Ok? Go fuck your mum, slut.

A comeback that can be funny if you use it at the right time, but not funny if you overuse it.
Good example:
Antonio: Who's doing cork? (For geography project)
Georgia: You mum is!
Mary: Is your dad's name cork?


Bad example:
Person 1: Hey, you penis is so small you can hardly see it!
Person 2: Your mum.

Not funny :|
