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!

A big ass chunk of hard snow, which you must avoid or jib off when snowboarding.

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.
