Action that occurs during sexual intercourse. Bronco Busting occurs when a guy is penetrating a woman while in the missionary position or doggy style. He has his friends hiding in the closet (planned before the sexual act will happen)and when he yells a code word such as "tokyo" the friends bust out of the closet, and te guy who is performing the sex act must try to stay on top of the girl similar to a Bull Riding Rodeo. This is where the act of Bronco Busting occurs.
