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.
