The clip comes from the Five Nights at Freddy's movie version of Foxy's dum dum song, featuring the red pirate fox animatronic from the long-running horror game series. After the film's release, fans clipped the catchy chant for short-form videos, edits and soundboards, where its mix of childhood nostalgia and horror made it instantly recognisable. It spread through FNAF meme pages and reaction videos, and it remains popular because it is short, quotable and instantly signals Foxy without needing a full jumpscare.
