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!
