Gay Best Friend. When a guy and a girl are extremely close friends and the guy puts her above all his friends even though they are in no way going out. For example, if the guy is with the girl and passes two friends hanging out on the street, he will completely ignore these friends and just keep talking to the girl.
Friend 1: Hey look it's Korman, is he coming over to say hi?

It’s an acronym for Garret Bobby Ferguson, who previously hold the universe record for Broken Bonez. His high score was 1,297,001. When he lost the universe record to Mordecai and Rigby, he exploded into a huge pile of goo. There was a time when his son was trying to revive him; so that they could get their revenge on Mordecai and Rigby, but they both exploded into goo.
GBF: It's the highest score in the whole universe, 1,279,001. Now who holds that record again? Oh yeah, me!
