The greeting comes from 'Whassup?', the Budweiser beer commercial first shown in 1999, in which a group of friends greeted each other on the phone with the same stretched-out word. The advert became a cultural catchphrase in the United States and was parodied in television shows, films and later internet videos. As short clips and soundboards spread online, the long 'wazzuuuup' version survived as a simple, instantly recognisable hello, used today mainly as a joke greeting rather than as a reference to the original advert.
