A guy who is a DICK! Someone who is a bad liar, two-faced, and can sometimes act like a chick; he either pretends to be gay with his "best friend" or actually talks like a chick. A guy who is an idiot and dates his ex-girlfriends or their friends. He is the guy in the group that no one likes. AKA a douche bag.
1. Sara:That guy over there stopped talking to me because I wouldn't give him a blow job.
Jen:What a Gage.
2. Something a Gage would say: Do these jeans make me look fat?
