The act of pouring microwaved kool aid on a male partners penis and then yell surprise! While your partner is screaming.
Ya I gave that bitch a kool aid surprise last tuesday. He'll think twice before cheating on me again.

And then I was fucking this chick and decided to give her the old Kool Aid Surprise, so I busted through her vaginal wall into whatever the fuck is in there, and then I was all like, "Oh yeeeeeeeeah!"
