A fork of Rural Dictionary
Intimate position, whereby the female's knees are drawn to the chest, with legs pointed straight up and feet turned out, like the handlebars on a motorbike. The male simultaneously grabs the feet and strategically "revs" the throttle, making motorbike sounds during the act, changing gears, and hitting the redline at climax!
Stan: How'd it go last night with the new girl? Kyle: It was awesome! She's a lightweight like a 150CC, so I pulled a Ricky Carmichael and motorbike'd it! (makes engine sounds and pretends to rev the throttle) I think I may have twisted her ankle!
