The sound draws on Undertale, the 2015 role-playing game by Toby Fox, and its fan-favourite skeleton Sans, whose knowing, fourth-wall-breaking humour made him a lasting meme figure. Fans began remixing Sans lines and time-travel ideas into short paradox edits, where a character is warned, released, or trapped by their own timeline. Those clips spread through gaming edits and meme compilations, and the format stuck because Sans already feels like a character who knows more than the player. That mix of lore, irony, and dramatic timing keeps the sound useful for new edits.
