dirtbiking 

The placement of one's face, specifically the mouth, into the area between a person's buttocks, followed by a rapid shaking of the face in a side-to-side motion, accompanied with an extreme exhale, resulting in the sound of a two wheeled motorized vehicle. See Motorboating.

So it turns out, Shit Faced and Dirtbiking are the same thing. Heeheehee

Is that shit on your lips or are you just happy to see me?

I've been dirtbiking so long, even Cookie Monster won't eat my chocolate chips.

Having a slut or pornstar on her stomach while pulling her arms backwards. At this point she sprays dung out her dirtstar like a rooster tail from a muddy dirtbike
