Ur sister a mister

The worst insult ever with indescribable punishment for the person it’s used against

Frank: ur dad lesbian
Harold: yeah well ur sister a mister
* frank and his entire family are wiped from the planet along with any memory of them. But the power used for this causes a great lightning storm transforming the whole world into thots. Then Stephen hawking comes back from the dead to begone those thots. Then he immediately dies of 7 different types of Ebola

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*
