cliffhucker 

Typically a skier, snowboarder, kayaker, or mountain biker who looks for steeps, drops, and ridges from which to jump. Cliffhuckers tend to be total adrenaline junkies who are always looking for that next ‘rush’. Some cliffhuckers have even died taking on drops that are simply too large or awkward to land.

Man, did you see that cliffhucker flip off that ridge up there? He totally bit it!
