Flowey is one of the most recognizable characters in Undertale, the 2015 indie RPG by Toby Fox. His laugh became a popular reaction sound among fans because it captures the character's manipulative, creepy personality in just a few seconds. The clip spread through gameplay videos, fan edits, and meme compilations, especially in posts that frame someone as secretly untrustworthy or theatrically evil. It still shows up in gaming memes because Undertale remains widely known and Flowey is instantly identifiable to players.
