Undertale Yellow is a fan-made prequel to Toby Fox's Undertale, created by fans and shared online as a free game. Flint is one of its original characters, and clips of his dialogue have circulated separately from the game as fans replay his scenes and share favourite moments. The sound has spread mainly through Undertale fan edits, gameplay videos and short meme clips, where a short recognisable voice line is easy to reuse. It remains popular because Undertale Yellow keeps attracting new players who discover Flint for the first time and want a quick way to reference him.
