Cthulhu is the vast, tentacled cosmic entity created by H. P. Lovecraft in The Call of Cthulhu, a story that has inspired games, films, and internet horror culture for decades. Short screams tagged with the name circulate on soundboards and in short-form videos as shorthand for encountering something ancient and incomprehensible. Creators keep returning to it because the name alone sets a dark, Lovecraftian mood before the audio even plays, making a two-second clip feel larger and more ominous.
