an annoying 2 stroke vehicle with a muffler note resembling that of a fart can honda civic on steroids, often driven by teens or young adults who feel they need to nearly hit every person or truck on the trails to act cool because of some form of self insecurity.
did you see that idiot on the Dirt Bike? he nearly ran straight into that parked truck flying down the trail, just barely missing the driver that had gotten out as well.
A sexual act in which a couple gorges on spicy Mexican foot in the evening in preparation for sex later that night. Later in the night, the couple engage in sex doggy style and the woman develops uncontrollable, blow out diarrhea. At this point, the man grabs her arms, pulls them back behind her, and revs her like a dirt while she sprays feces all over the both of them (much like revving a dirt bike stuck in the mud)!
I knew Carla was kinky when she agreed to perform the dirt bike with me.
