This is five times worse than ur granny tranny. Every time this is said the fabric of space a time rips.
Bob: ur mom gay and ur granny tranny.
Josh: Don’t make me say it bro.
Bob: you won’t Bitch.
Josh: ur sisters a mister.
*Bobs head explodes and the fabric of time and space rips destroying Jupiter*
An insult that you can use instead of ur mom gay or ur dad lesbian.
Bob: Hey Steve ur mom gay
Steve: Oh yeah? Well ur dad lesbian
Bob: Ur sisters a mister
Steve: *all brain cells explode and Steve fucking dies*

Frank: no u
David: ur dad lesbian
Frank: ur granny tranny
David: ur grandpap a trap
Frank: ur sister a mister
David: *explodes into oblivion and his soul is being eaten by minecraft youtubers*

A very dangerous phrase, not to be used lightly. Has risen from other primitive phrases such as ur mom gay, and ur daddy lesbian.
Carl: Ur mom gay
Dylan: ur granny tranny
Carl: ur sister a mister

This word is only used after your vicious enemy uses the world ending saying “ur pappy trappy”. “Ur sister a mister” can reverse the world ending and causes a blackhole to suck the earth into a bottomless pit of darkness.
Bill-ur pappy trappy
*world starts to end*
Jon-ur sister a mister
*world stops ending, and blackhole shows up infront of the sun*
Stephen Hawking- my theory was right. Only the mere saying of “ur sister a mister” can cause a black hole

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
