A descriptive word for what happens if
one falls at the top of a hill - or loses
one's nerve - and slides in a vaguely controlled manner on one's
bottom all the way to the end. Also can be used as a verb, as in "ratballing."
I accidently found myself on a black diamond ski
run and decided to ratball my way to the
bottom.
As we were descending from the mountain, we ran into a patch of
loose rock, and decided to ratball rather than risk falling.
