Gtfo
From KGB Wiki
Pronounced "git-fo," gtfo is often said at the end of meetings to encourage the migration of members to other places. GTFO stands for "Giant Tetrahedrons Flocking Outside" and inspires members to rush outside to see this impossible event. The Exec takes this opportunity to cackle loudly and lock the doors behind them, so the general body members shrug and scatter for the week, often heading off en masse to get food.
Alternate explanations of this gtfo phenomenon exist, but are lies and should not be trusted.
