Friday Night Funkin' is a free rhythm game first released in 2020, where players press arrows in time with music to win rap battles. Its bright, retro interface and catchy songs helped it spread quickly through YouTube, Twitch and TikTok, turning many of its menu and gameplay sounds into familiar memes. Short clips like this click are widely shared on soundboards because they are instantly recognisable to fans, easy to drop into edits and useful for signalling a selection without needing any dialogue.
