The sound comes from Five Nights at Freddy's, the indie horror game released by Scott Cawthon in 2014. Freddy Fazbear is the main animatronic mascot, and his nose honk began as an Easter egg on the in-game poster and later on Freddy himself. Players shared clips of the discovery online, and the boop became one of the series' most quoted jokes across sequels, streams, and fan videos. Its lasting appeal is simple familiarity: FNAF fans recognize it instantly, while everyone else hears a harmless squeak.
