Comes from the musical instument (Drums) played by the member of a band, usually sits at the back of the stage. Without this godlike creature there would be no rythem to the music and havoc would incurr.
Plays with the precise action that only a master craftsman can obtain. Thats right, with sticks. Only people with the right personality combination can become a drummer. That person blessed will also probably have to owm some sort of 'kit' to play with. And although guitarists are cool, there're one-hundred a penny. Sadly.
