decemberists 

The Decemberists are one of the best indie rock/folk bands out there. Keep an eye out for their soon to be released album "Picaresque". It has "The mariners revenge" track, which is possibly the best lyrical song ever written.

You: Hey, I'm bored of my music, got a recomendation?
Me: Check out the Decemberists, they're amazing.
You: K, thanks.

The latest album by AFI (A Fire Inside). Although different from their previous albums, it still kicks ass. Often dissed on by closed minded fucks that only accept AFI's older albums.

closed minded fuck: "oh god!! i hate hate hate AFI's new album!! i love "old school afi" better! they disappoint me!"
me:"uh, ya.. you need to cheer up and get over it. ill talk to you later.. im going to go listen to decemberunderground."

Decemberitis 

Decemberitis is a late NFL season disease that affects the Wade Phillips Dallas Cowboys during the month of December. Symtoms include, inability to complete passes, chronic interception syndrome, being sacked multiple times, random loss of hand-eye coordination in clutch situations, poor performance in the playoffs, and general embarrassment in the eyes of the local media.

There is no known cure and those who suffer from Decemberitis are doomed to a career of mediocrity.

After a pitiful display by the 2009 Dallas Cowboys and the lack of production during the 2010 season in the month of December, it appears that there is still no cure for Decemberitis.
