Sister Mama

Two baby mamas who share the same baby daddy. The baby mamas are friends and have good relationships with all their children and each other's families, without the baby daddy.

My baby daddy gets jealous that his two ex's get along and have become Sister Mamas, who act like positive loving adults for the sake of their children.

Sister Twister

When you put your dick in your girls ass, and proceed to spin her like a helicopter blade. Doesn't have to be your sister, but it can be. Works best with small girls as they are easier to spin.

I had a dream last night me and Mila were doing the sister twister when my dad walked in.

Ur sister a mister

Only use this phrase if you are prepared for the consequences. This phrase is the offspring of “ur mom gay” and “ur daddy lesbian,” and the breeder of it was Satan himself. It is the worst thing that you can say to someone. If the arguments gets to “ur grandpap a trap” and it’s your turn, chain yourself down before you use this. It’s deadly.

Steve: ur mom gay lol
John: no u
Steve: ur dad lesbian
John: ur granny tranny
Steve: ur grandpap a trap, ha, no coming back from that!
John: *chains himself down while fire sprouts from every hole of his body*
UR SISTER A MISTER!!!!!!!
Steve: *explodes into atom size pieces that are on fire as Satan pulls his soul down past hell to the unknown
God: *tears pour down his face* holy shit!
