The space between your helmet and your goggles exposing your forehead while skiing. Extremely bad gorby gaps can show over an inch of forehead, and sometimes even have strands of hair falling over the person's goggles. Gorby gaps can be caused by a bad fall, or the person just not knowing any

gap and will be laughed at, but gorby
gap is almost always seen on a Gorby.
"You just packed crap dude, you
better fix your goggles you've got a gorby
gap."
