A crazy group of people who play awesome music with shiny instruments at athetic events. Usually their music is heard so often that even the football players have the songs memorized. The drum major leads the pep band by waving his/her arms in random motions to make it look like the band is actually watching him/her.
We're playing that song for pep band AGAIN this year?!
The referee got totally pissed off when the pep band played more than just durring time outs.
