Get the Ur sister is a mistermug. An insult meaning that your sister is actually a transgender man. This insult is so rare it has only been said by 4 people and was buried in the Egyptian pyramids to never see the light of day.

Get the Ur sister a mistermug. 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
