Supermini Dirtbike 

A supermini is a stock 84cc mini (usually one of the five major dirtbike brands) with a modified cylinder of 100, 103, 105, 109, or 112cc's. These dirtbikes also have a 16" rear wheel and a 19" front wheel as opposed to the normal 14" and 17" wheels on a stock 85cc bike. These bike's ate the perfect transition bike from a mini to a full sized bike. Often, a skilled rider on a supermini can catch and pass an adult on a full sized bike.

"dude did you watch number 111 on the Yamaha supermini dirtbike?"

"ya, he was doin the 90 foot triple jump that most of big bikes won't even do!"

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.
