look up any word, like donkey punch:
it's when you are doing it doggy style and your friends are hiding in the closet...they jump out and yell "SURPRISE!!" and you have to hold on and stay in her for 8 seconds
"Biff and Brad are coming over and we're going to pull the Bucking Bronco on Amy...it'll be hillaaarious, I'll say I didn't know-she won't believe me-and then I won't have the awkwardness of breaking up with her! Perfect plan!"
