Bugmeat
From A KoL Wiki
Bugmeat is the term for meat that has entered the game through an error, or 'bug', in the game code. Much of KOL's bugmeat appeared on Black Sunday (August 8th, 2004), the day that a major meat creation bug was found and widely exploited. The bugmeat was created by using a meat vortex from your inventory while having no meat. Instead of failing to work, it gave you a bunch of meat instead. This has since been fixed. Most bugmeat is removed from the economy through the use of meatsinks, most notably the Penguin Mafia storyline not long after Black Sunday.
