A variant of Xtreme Kool Letterz, seen used in both work titles and in names.

The letter X is already fascinating and cool, so double the X, double the awesomeness! Right? Much like Xtreme Kool Letterz, it's often meant to evoke badassery, or lend the show an air of youthful hipness and coolness.

How exactly are you supposed to pronounce this is usually unclear.

Examples of Double X include:


  • The Most Interesting Man In The World doesn't always drink beer, but when he does, he prefers Dos Equis ([1]). Stay thirsty, my friends.

Card Games

  • Fluxx

Comic Books



Live Action TV

  • The spaceship Lexx, from a series of the same name.
  • German game show GoXX.
  • The German show Reläxx.
  • The main character (and host) of Double the Fist, Steve Foxx.

Real Life

  • The company Blaxxun (originally spelled "Black Sun").
  • Exxon Mobil Corporation.
  • Minolta Maxxum cameras (now Sony Alpha).
  • Redd Foxx (real name: John Elroy Sanford)
  • As a tribute to Redd Foxx, actor/comedian/singer Jamie Foxx (real name: Eric Marlon Bishop)
  • XXX-rated movies. This is really just a marketing gimmick, implying "X" is dirty. (Even if a lot of legitimate films were rated X.) And that "XXX" is three times dirtier.
