In the bronco buster, an opponent is seated in the corner of the ring while the attacking wrestler jumps in the corner, straddling his or her opponent's body, and bounces up and down on the opponent's chest. The bronco buster is normally treated as having comic or sexual connotations rather than as a legitimately painful move.
X-Pac made this move famous in 1997. Tygress performed the move in WCW where it was referred to as "Face Full of Stuff." Maria Kanellis and ODB also use the bronco buster.
