I feel like I say gaper more often, but I believe there was a thread like a day ago about this same thing where someone said something along the lines of, "the difference between a gaper and a Jerry is that a Jerry thinks they know what they are doing".
To put everything into terms:
A Gaper and a Jerry are kind the same thing just a newb or jenky person fucking everything up on the slopes.
A Joey is a Gaper or Jerry in bike terms.
Gaper/Jerry = Ski/Snerrberrd
Joey= Mtn Biking
