The phrase comes from Danielle Bregoli's appearance on Dr. Phil in September 2016, where the then 13-year-old challenged the studio audience with the line cash me outside, how bout dah. Clips of the moment spread rapidly across YouTube, Vine and Instagram, spawning remixes, reaction videos and merchandise, and turning Bregoli into an internet celebrity who later recorded as Bhad Bhabie. The shortened how bout dat version survives because it works on its own as a defiant dare, instantly recognisable even to viewers who never saw the original interview.
