Dirt Biking is the act of having sex with a woman on all fours. While in the act, the male slips his thumb into her anus and then makes motorcyle sounds while pumping the "throttle". The time that elapses from insertion of thumb until the time you get thrown off is to be compared amung buddies.
"Hey man, the other night I dirt biked her for 54 seconds. funny thing is, she never called me back".....

Get the The Dirt Bikemug. 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)!

Get the dirt bikemug. 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!
