When you stick your arms out in front of you as if you were dirtbiking, then pretend to ride a dirtbike by running around and making loud and obnoxious dirtbike sounds at the top of your lungs in a public area. May be accompanied by dirtbike gear. Usually, a bout of dirt biking is accompanied by wipe-outs, where you do a spectacular crash and make sputtering sounds. Afterwards, you can pick up the bike and do a sweet wheelie to get out of there.
Guy 1: Man, did you see that plank I did?

Guy 3: Ya, I just went dirt biking in Wal-Mart!

The Dirt Bike Strictly for pros. This is when you have the girl on all fours, and you grab her wrists and pull her arms out while she is spraying diarrhea out (thus giving the image of you riding a dirt bike).

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.
