Ur sister a mister

You do not want anyone to say this to you. This is the best roast in the entirety of all roasts. Worse than ur mom gay, ur dad lesbian, ur granny a tranny and ur grandpap a trap combined.

Lobster: Yo ur mom gay and ur dad lesbian.
Egg: No u.
Lobster: No u x3.
Egg: *OOF* Well ur sister a mister.
Lobster: *gets engulfed by the sun and dies*
