What is The Slippery Rhino?
1.
A sexual act in which the woman is placed on all fours. The man then utilizes a strap on penis and attaches it to his forehead. He then backs up a distance of about 10 feet and charges into the woman inserting the strap on into either hole (doesn't matter which).
Person 1: Yo i heard she got the slippery rhino from him last night
