I'm just curious, as the term "your mom" as an annoying answer/reaction to any question/comment is also used in other languages. So what is its etymology?
I even found a reference on Serverfault.
Maybe it wasn't that clear what I meant, so I give two examples taken from the urban dictionary:
Guy 1: I'm going to tie my shoes
Guy 2: YO MOMA'S GONA TIE HER SHOES!!!
Girl 1: That Girl is a slut.
Random Guy 1: YO MOMA'S A SLUT!!!
I even remember an Episode from Miami Vice (season 3, maybe episode 22) where Crocked asks for the whereabouts of a suspect and he gets a kind of "Your Mom" as an answer.
Here's another reference:
