Joe: ur mom gay
Tim: no u
Joe: UR DAD LESBIAN

Tim: UR GRANNY TRANNY
Joe: UR PAPPY TRAPPY
Tim: UR SISTER MISTER
*At this point time ceases to exist. The very fabric of the universe has be torn to shreds, the entire 3rd dimension is incinerated and all life on earth ceases to exist*

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

Ur sister is a mister 

An insult worse than than ur mum gay, ur dad lesbian, and ur granny tranny. This is the worst insult imaginable and there is absolutely no recovery from it.

Grant: ur mum gay
Mark: ur dad lesbian
Grant: ur granny tranny
Mark: oh yeah, well ur sister is a mister
Grant: *all veins inside body explode, has a seizure that causes him to pull out a gun from his jacket, and blow his own brains out.
