Beetlejuice comes from Tim Burton's 1988 comedy horror film Beetlejuice, where Michael Keaton played the mischievous ghost Betelgeuse, summoned by saying his name three times. The film became a cult favourite, leading to an animated series, a stage musical, and a 2024 sequel that renewed interest in the character. Short clips from the performance have circulated online for years as reaction sounds and Halloween edits, because the voice and attitude are distinctive enough to carry a joke without any scene setting or explanation needed.
