Dirt Biking

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!

Dirt Biking

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.

dirtdicking 

The act of getting so drunk or high that one's figurative "dick" gets knocked in the figurative "dirt."

Making a grave mistake that results in a figurative loss of one's status, dignity, or respect.

"He was so drunk last night that he ended up dirtdicking his own birthday party by passing out before the cake was even served."

"I can't believe I lost that job over something so stupid. I really dirtdicked that one."

"I was really nervous about my job interview, but I ended up dirtdicking it by showing up late and forgetting my resume."
