Acronym for "Good luck in the offseason bitch". Used as a slam against your opponents in Fantasy Football. It's a way to humiliate your opponents by congratulating them on their long offseason while you play on in the playoffs. First used by Dewayne Bruce in Corruption chat, to congratulate Gian Musarra on his early vacation.
Hey, that was a tough loss this week. GLITOB!
