This sound comes from Undertale, the indie RPG created by Toby Fox and released in 2015. Its simple retro effects became familiar to players through battles, menus, and repeated encounters, which helped short clips like this spread in edits and meme videos. Online, the damage cue is still used because it communicates an instant loss or misplay in less than a second. It often appears in compilations of game sound effects alongside recognizable cues such as the ROBLOX oof.
