Lovely Kiss began as a Pokemon move in the first generation games, most closely associated with Jynx, where it puts the opposing Pokemon to sleep instead of dealing damage. Pokemon Stadium for the Nintendo 64 brought the move to life with animated effects and this short smooch sound. Clips of Stadium battles later circulated on soundboards and in fan edits, and creators kept reusing the cue outside battles. Its mix of a cartoon kiss and a sleep move makes it useful as shorthand for instant attraction or being knocked out by love.
