your sister a mister

your sister a mister is possibly the worst insult ever created. It will destroy an entire dimension whenever it is used. Another language had to be made to create this phrase, and this is the rough translation. Calling someone's sibling trans is easily worse than Your mom gay, Your dad lesbian, Your granny tranny and Ur grandpap a trap are hardly insults copared to your sister a mister.

God: Are you a little bitch?
Me: Your sister a mister
God: *Fucking dies on the spot

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
