Definition

Affectionate shorthand for Tenacious D, the comedic rock duo of Jack Black and Kyle Gass who turned power ballads about Satan and friendship into an art form. What started as a self-proclaimed 'greatest band in the world' joke became a legitimate cult phenomenon. The 'D' stands for destiny, obviously.

Example Usage

I've had 'Tribute' by The D stuck in my head for three days straight.
