When you make yourself a bath and you obtain an erection. Once an erection has been obtained, grab your penis by the bottom of the shaft and push it forward, hitting the water and bring your penis back up just as quickly as you pushed it down. Doing this motion enough times makes your penis look like the Hungry Hungry Hippo from the popular board game.
Guy 1: Dude, the other night, i did the hungry hungry hippos in the bath.
Guy 2: Dude, thats fucking epic!!!
Guy 1: Thats why I did it!!!
