Big Easy: I was shooting snot rockets on golf course the other day. They were so big, I was filling divots.
Stoney: That’s dope. I was shooting cum rockets the other day. They were so big, I could fill whores with them.
Big Easy: I wanna be like you when I grow old.

The act of being tossed around like a dirty cum sock between the KKK members as they take turns gangbanging you before finishing in a jar. Whoever lasts the shortest period of time has to drink this entire jar of delicious warm beverage.
Deshaun: "Bro I got caught by the OPs last night and they took turns pounding on me, turns out they were playing Ku Cum Klan and one of the niggas started drinking my load, was kinda kinky"
