SG (sincere girl) that a girl will down on her own social status or beauty to gain a compliment or recognition from a guy. Also trying to get a guy to compliment for her own self esteem.
As the SG says "I'm fat and I'm not good enough for anyone" the replies with a sincere comment "your not fat or ugly, your pretty cute". Gaining a compliment from the opposite sex.
