look up any word, like bukkake:
A big ass chunk of hard snow, which you must avoid or jib off when snowboarding.

A rather large nugget of snow/ice that is formed either by ski resort groomers or broken off of a cornice

From Mountain/Dirt Biking. Irregularly shaped rocks about 3 to 6 inches in diameter. Too big to roll over easily like gravel and too large and unstable to balance on. Just smaller and less dangerous than the dreaded baby head.
Dude, I kept my shit together on that stretch of death cookies but I ate shit completely when I hit the baby heads!

Reflector bumps in the middle of the road that try to fuck you up while you are carving your longboard.
I managed to weave in between the first few death cookies but the twenty-second one sent me into irreversible speed wobbles.
