Double X

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.
