When you are having anal sex with a girl, whisper in her ear you have AIDS and try to ride her like a raging bronco.

while dukeing a girl, have a friend hide in the closet and suddenly jump out and frighten the girl so much that she will begin to rage around the room while you grasp on to her shoulders and attempt to stay on as long as possible

You guys are close...It's when you're out at a club you find the fattest nastiest chick there. Bring her home and start giving it to her doggy style. Once you have a firm grip and a wide stance scream out "You are the foulest bitch I have ever seen!" and slap her in the face. Then try and hold on as long as possible as she tries to throw you off.
I struck out with lacy at the club last night so I took some hog home and had me a nice buckin bronco.

While having sex doggy style, the male very subtly wraps the female's hair (preferably long) around his hand. However, the stimulus for the bucking is not an insult from the male, but as Buckin Bronco purists will attest, when the rider's friends burst into the room (from a closet typically) ringing cow bells and cheering wildly.
See that skinny dude over there. Last weekend, at a party, he pulled 12 seconds on a nasty little Buckin Bronco.

Upon the act of coitus of the "doggy" variety, the male partner (cowboy) grabs the hair (mane) of the female partner. In this instance the female partner will be referred to as a Bronco. At this point, the cowboy, whilst maintaining a firm grasp of said mane, yells (in a western drawl): "I have AIDS, syphilis, fleas... ect." Soon thereafter, the Bronco, in a futile attempt to escape the "8 second ride", will start the buckin' process. This is known as the "Buckin' Bronco"!
In a feeble attempt to dislodge my tube-steak from her gully-hole, she flailed and kicked like a buckin' Bronco. Yeehaw!!!

A buckin bronco is when your friends hide in a closet in a bedroom. You bring your chick upstairs into the same bedroom and start fucking her as your friends listen in and/or watch. You when get her in doggy style you say a trigger word like "sweet" something that is not out of the norm for sex. When your friends in the closet hear this they jump out screaming and one times how long you can ride her as she is trying to buck you off
