Flowey is the first character players meet in Undertale, the independent role-playing game released by Toby Fox in 2015, where he initially poses as a helpful guide before revealing his cruel nature. His laugh became closely linked to that twist, and clips of it spread through gameplay videos, memes and soundboards as shorthand for a false friend turning evil. Fans still reuse it because Undertale remains widely played and discussed, and the laugh instantly recalls Flowey's unsettling shift from innocent flower to threatening antagonist without needing any dialogue.
