50 Cal.

A sex move where the girl does a handstand and the guy fucks her in the ass, while pulling her legs towards him to make it look like he is shooting a 50 Cal. machine gun.

- Remember that girl last night?
- Yeah. What about her?
- I 50 cal.'d her in Jonny's room!
- That was my sister you motherfuker!
