Beastymoto 

The art of riding a motorcycle that is far more suited for paved roads on rough, wash-boarded, unsurfaced, and often unnamed roads. Also includes water-crossings.

Did you see that guy acting like a mad neanderthal tearing up his street bike on that dirt road?

Yes, he is just trying to be a beastymoto
