The jumping hippo is when a fat bitch rides you with the cowgirl or reverse cowgirl. This is a very dangerous maneuver because you might snap your dick or break your pelvis.
Guy 1: Yo, I was with this fat bitch and she did the jumping hippo
Guy 2: Bro, are you okay?
Guy 1: Nah, my dick went 90 fucking degrees and it's stuck like that.
Guy 2: Oh shit.
Guy 2: Bro, are you okay?
Guy 1: Nah, my dick went 90 fucking degrees and it's stuck like that.
Guy 2: Oh shit.

First have a hard running start, jump, put your non dominate foot and hand on the wall or whatever your jumping off of, and push off and land on somebody. Best you jump off of brick
