The phrase comes from Danielle Bregoli's 2016 appearance on Dr. Phil, where her pronunciation of 'Catch me outside, how about that?' became a viral quote. Short clips spread across YouTube, Vine compilations, and reaction memes, turning it into a staple for confrontational humor. It is still used because the line is brief, instantly understood, and perfect for edits built around trash talk, exaggerated confidence, or a sudden challenge.
