this is acutally an acronym that stand for Guaranteed Accident Prone on Every Run. Referring for a skier or snowboarder, usually wearing bright 80's ski gear that cannot ski or ride, or a tourist in a mountain town who walks around with their mouth agape in awe of the mountains!
That gaper got out of control and crashed into a tree!

Those gapers are stopping traffic standing in the middle of the street taking a picture.
