The 'Whassup' greeting exploded in 1999 through a Budweiser commercial where friends shouted the drawn-out word over the phone, making it one of the decade's most quoted ad catchphrases. Scary Movie, the 2000 horror spoof directed by Keenen Ivory Wayans, borrowed the gag for its opening scene, with Ghostface greeting Cindy Campbell with the same elongated 'Wazzup' before threatening her. The mash-up of a famous beer ad and a horror icon cemented the line in soundboard culture, and it still resurfaces every Halloween in edits, prank calls and costume videos.
