The phrase began with the 1999 Budweiser wassup adverts, but this drawn out version comes from Scary Movie in 2000, where Ghostface and his friends trade the greeting on the phone while stoned. The scene turned a beer slogan into a defining early 2000s catchphrase, copied in schoolyards, ringtones, and early internet videos. It survived as a meme sound because the delivery is instantly recognizable even without the video, making it a shorthand for a goofy, overfamiliar greeting among friends online.
