Essentially, flipping the hippo is a clean term that refers to sexual activities. The term is used as a verb phrase, and is often used to discretely discuss the weekend's activities without snoopers finding out your intentions.
(Friend to Friend, with others nearby) - We went out to dinner, and then that night we were flipping the hippo until she had to go back home.

Dude! Did you and Sasha flip the hippo last night? You were gone for hours!

Sorry I couldn't hang out yesterday, I was really sore from flipping the hippo with O'Glory.

I was thinking we could do something special tonight... Maybe some white wine, some turkey, we could flip the hippo--what do you say Willis?
