Beetlejuice is the chaotic ghost from Tim Burton's 1988 film Beetlejuice, played by Michael Keaton, who later returned in an animated series and in the 2024 sequel Beetlejuice Beetlejuice. The character is known for loud, theatrical entrances and a mischievous sense of humour, which made his vocal sounds easy to lift into short clips. Online, the elongated call circulates on soundboards and social video as shorthand for a spooky entrance, especially around Halloween, because its recognisable tone works even without the film footage.
