Moon Landing

A form of prank executed in male locker rooms where one individual, while they have their bare ass out, jumps and tries to land their ass as high as they can on the unsuspecting individual. Bonus points awarded for making it to their head, but points subtracted if said person is of a shorter stature.

Jake: Damn, Bryan hit me with a moon landing on my head earlier in the locker room today.
Chris: Yeah, but you're like 5'8 so that's not really all that impressive.
