Ghostface is the masked killer from the Scream franchise, first seen in the 1996 film, known for taunting victims by phone before attacking. The drawn out wassup greeting is most associated with the 2000 parody Scary Movie, which exaggerated that phone persona into a goofy catchphrase. Clips of the line later spread through YouTube edits, Vine and TikTok soundboards, and Halloween costume videos. It stays popular because it mixes instant horror recognition with a silly greeting, giving creators a shortcut for prank calls and ironic scary moments online.
