A sex act where a woman is laying flat on her chest while a man is having anal sex with her. Then he has to put both his hands secured in a place he can grasp on to the woman. He the procides, as he is in "action", to whisper in the woman's ear "I have Aids". If proformed correctly, the woman will try to shake the man off her by trying to jump up. The man shood try to stay on for the full effect. Don't use unless you plan to break up with the girl.
I pulled the Bucking Bronco on her and she practically jumped out the window!
