The sound comes from Budweiser's Wazzup advertising campaign, which began in the late 1990s and became a major pop-culture catchphrase after its Super Bowl airing in 2000. The ads showed groups of friends greeting each other with the stretched-out word over the phone, and audiences quickly picked it up, quoted it in everyday conversation and parodied it in other shows and videos. Decades later, the greeting still reads instantly as a piece of early 2000s nostalgia, which keeps it in circulation in memes, reaction edits and throwback compilations.
