Sister Flow

Sister Flow- A softer way for a woman to refer to her period, monthly bleeding and/or menstrual cycle. In particular a word to use when her man wants some and the timing is not right so he cant have some.

Sorry baby not tonight; sister flow is home.

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
