When you are doing doggy style during sex, you reach over and grab hold of the womens shoulders. After you tell her you have Aids or STD's and you ride her untill she can get you off, looking like an angry bull.
When Burock told his girlfriend Felica he had Aids during doggy style she tried to fight him off looking like a angry bull. or also known as bucking bronco

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.

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.

You're doing a girl doggy style and you lean up and whisper in her ear, ""I have AIDS". She starts hopping around and you see how long you can stay on.

When you are giving a girl anal, you stay inside her and tell her you have AIDS, and see how long you can hold on to her.

When having sex doggy style and the person in the back says something that makes the person receiving want to get away. It could be another person’s name, saying they have HIV, saying they just had sex with a dead person, etc. The goal is to have the receiver try to get away and the other person rides them for as long as they can. Rape. It’s basically rape.
When John was fucking, me he said he had HIV. I tried to get away, but he was then raping me while trying to do that bucking bronco thing.

None of you got it right. A bucking bronco is... when you are having sex in a car, typically sitting in the front seat with the woman straddling your lap (it works best if she's facing you so she can't see what you're doing), you push in the cigarette lighter and when it pops out you quickly touch it to her ass cheek for a second. Naturally she will buck up and down and try to get off, and you have to grab hold and keep her on you.
"Man, me and Cheri where in my car last night getting it on, and I gave her a bucking bronco. She was pissed off but it was a great ride!"
