It often referred to an event or problem that was “up.” Later iterations, including wassup, whassup, whaddup, and wazzup evolved from slurring the consonants of the original phrase. These iterations first came into use in the early 20th century. What’s up was further brought into the popular lexicon by Bugs Bunny, a cartoon rabbit who premiered to great popularity in the 1940s. Bugs Bunny’s signature greeting was “What’s up, Doc?” The creator of the cartoon claimed it was a common phrase in his Texas hometown. Originally used to cheekily address Bugs’s longtime nemesis (cartoon hunter Elmer Fudd), the catchphrase became well-known to Bugs’s large audience and was widely adopted. Whassup was also the catchphrase (and pun on wasabi) in a popular 1999 Anheuser-Busch Budweiser beer commercial campaign. The campaign was based on True, an award-winning short film created by Charles Stone III. Then, in 2000, Scary Movie created a whole scene around one phrase: wazzup. The widespread exposure further cemented the popularity of wazzup and what’s up in pop culture. Examples of what’s up What’s up with WhatsApp on Blackberry and Windows Phone?
