The 'Tunnel Snakes Rule!' meme originated from the 2008 action RPG Fallout 3, specifically centered around Butch DeLoria and his childhood gang in Vault 101. While the phrase was a minor part of the game's introduction, it reached legendary status in 2009 after a fan-made website featured a repetitive, catchy techno-remix of Butch's dialogue and animations. The meme captures the hilarious overconfidence of a group of pompadour-wearing greasers trying to act tough in a post-apocalyptic bunker. Today, it is used by the gaming community to signal nostalgia for the Fallout franchise or to mock groups that display an unearned sense of superiority or coolness.
