Let's Rev It Up is the English dub catchphrase of Yusei Fudo in Yu-Gi-Oh 5D's, the third Yu-Gi-Oh series that aired from 2008 and centred on Turbo Duels fought on motorcycles called Duel Runners. Yusei says the line before duels, signalling speed and resolve. Clipped from the show, it spread on soundboards and in fan edits alongside other iconic anime catchphrases like Za Warudo and Tuturu. Its short length and clear build make it easy to reuse as a hype button long after the series ended.
