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 2: Planking? Everyone knows dirt biking is where it's at!
Guy 3: Ya, I just went dirt biking in Wal-Mart!

When one person lets there asshole get all disgusting and dirty, then another has butt sex with them (usually done messy)!
1) Dirt Biki- My ass feels so gross, but it will be worth it tonight when I get dirt biked!
2) Dirt Biker- Man I can't wait to go dirt biking tonight.
(friend) -Wow, thats pretty sick.

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".....
