The line comes from Saturday Night Live, where Kenan Thompson hosts the recurring What's Up With That sketch as Diondre Cole, a talk-show host who constantly derails his own interviews with musical numbers and running jokes. The sketch became a fan favourite for its chaotic energy and Thompson's exasperated delivery, and clips of the catchphrase spread through reaction videos, memes and edits. It endures because the question works for almost any confusing moment, instantly framing it as comedy.
