During sex, the male is on the female can be many different positions, and while he's in her, he holds her hands/arms/or anything else to keep her down while he's busy fucking her, then says something like: "I have AIDS," or "your best friend was better," etc. She then tries to get away as fast as she can. As the female is trying to get away, her frantic movement is making his dick go deeper inside her, at a faster rate.

Sex move in which the girl has pigtails, and you have doggy style sex, then at the peek of the male's orgasm, he whispers into the girls ear, "I have aids" then the male sees how long he can keep it inside.

WARNING DO NOT ATTEMPT, THIS IS A JOKE, IT CAN CAUSE PSYCHOLOGICAL DAMAGE AND OR HAVING YOUR DICK SNAPPED OFF.
No example cuz you shouldn't try the Bucking Bronco if you would like to keep your dick attached to your body

Similar to other definitions, the bucking bronco is when you are fucking your girl doggy style, you then make a smart comment(ex. "I have AIDS" or "Your sister was better" and see how long you can stay on for.
You are banging a random chick you met that night, doggy style. While it's all goin on you whisper in her ear,"I have AIDS," then let the ride begin and see how long you can stay on that bucking bronco for.

The new, upcoming trend brought on by the younger generation. It involves one male thrusting a random male to the ground, then jumping on him and doing it from the back very quickly, until the other person fights back.
