A homosexual saw a handsome straight man walking by and follows along trying to get into the "friend zone" only so that when they go on an overnight trip he can jump on that mans ass!
Guys best friend: Dude, he is so gregging on you right now.
The act of dogging while inside a gondola (large ski lift). The aim is to make people in lifts passing in the opposite direction watch you have sex, consequentially causing arousement for the participators.
Me and the bird had a spot of gogging on the way home from skiing today.
