Bucking Bronco 

NOUN. When a girl is on top riding the man, and he grabs her by the waist, his buddies open the door and start cheering. It is at that moment when the girl will try to get off. The man will then see how long he can hold her on.

At Club O last night, in the bathroom, Sebastian set the record with a 37 second Bucking Bronco.
