Ur brother's A mother

The ultimate insult. Nothing compares to this. It trumps over ur mom gay, ur dad lesbian, ur granny tranny and makes your grandpap A trap look like "ur stupid".

1: ur mom gay

2: no u

1: well, ur daddy lesbian

2: ur granny tranny

1: noooo, your grandpap A trap

2: you made me do this. (Grows into a giant and raises his hand to the heavens) UR BROTHER'S A MOTHER!!!

(2 brings their hand down and vaporizes 1, then the entire galaxy speeds toward andromeda galaxy at the speed of light, causing a massive black hole that swallows the universe.)
