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!"
