The Tunnel Snakes are a small gang in Vault 101 in Fallout 3, released in 2008, led by Butch DeLoria and known for their leather jackets and rebellious attitude. Their catchphrase, Tunnel Snakes Rule, became a running joke among players because the gang is more posturing than powerful. Clips of the chant spread through Fallout fan videos, edits and meme pages, where it is now used far beyond the game itself as shorthand for a group that takes itself far too seriously.
