Ur sister a mister 

Only use this phrase if you are prepared for the consequences. This phrase is the offspring of “ur mom gay” and “ur daddy lesbian,” and the breeder of it was Satan himself. It is the worst thing that you can say to someone. If the arguments gets to “ur grandpap a trap” and it’s your turn, chain yourself down before you use this. It’s deadly.

Steve: ur mom gay lol
John: no u
Steve: ur dad lesbian
John: ur granny tranny
Steve: ur grandpap a trap, ha, no coming back from that!
John: *chains himself down while fire sprouts from every hole of his body*
UR SISTER A MISTER!!!!!!!
Steve: *explodes into atom size pieces that are on fire as Satan pulls his soul down past hell to the unknown
God: *tears pour down his face* holy shit!

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

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*
