Wooimbouttamakeanameformyselfere is an unspaced version of "Woo, I'm about to make a name for myself here"—a line spoken by Gambit in Deadpool & Wolverine. The character, played by Channing Tatum, speaks in a Cajun or Creole accent and drops the quote rapidly without pause.
Days after the film was released to general audiences, a Twitter user started a meme by quote-tweeting a clip of this moment and repeating the line in text, written to sound more like it was spoken in the scene.
