Someone who is so incredibly obnoxious that they make one’s stomach turn (or make one ‘gag’). This type of person could have delusional tendencies, grandiose behavior, be a pathological liar, may have a tendency to exaggerate and alienate one’s friends.

If someone does or acts in such a behavior or displays this behavior one could be acting like a GG or doing a GG. Also, if one sees behavior that displays these qualities they could want to GG (gag due to seeing this particular type of behavior)

Lady #1: Oh, Carol is so mean! Did you see how she yelled at me like that? Lady #2: Girl, don’t you be pulling a GG on me, you know she didn’t yell!

John Doe: Did you meet Tom at the board meeting last night? I almost GG’d after listening to him go on and on about himself.
