Hossin- The act of going as fast as possible over crappy terrain, (refers to sports such as snowboarding, longboarding, driving, mountain biking, etc...) usually refers to the utmost speed one can achieve before entering a feature or manuever. It is not just the act of traveling fast, but the art of going faster then safe, during a particularly sketchy section, before a turn, jump, trick, etc.

Hossin- If you have to hit a mandatory fifteen foot jump before you have to straight line a chute with moguls in it and then hit a seventy foot step down with a river between the lip and landing, you are hossin.
