Megalovania is the fast, dramatic boss theme associated with Sans in Toby Fox's Undertale, first released in 2015, and it has since become one of the most remixed video-game tracks online. Its urgent melody is instantly recognisable even to people who have never played the game, which makes it a ready-made shorthand for an overblown confrontation. Meme editors have built countless parodies and mashups around it, and this pluh version leans into that joke by swapping heroic intensity for flat indifference, keeping the tune familiar while changing its attitude completely.
