Michael Ryan Pritchard, better known by his stage name Mike Dirnt, is an American rock musician who is the co-founder, bassist, backing vocalist, and occasional lead vocalist of Green Day. He has also played in several other bands, including the Frustrators. His stage name Dirnt was originally a nickname that his friends from grade school gave him, as he constantly played "air bass/guitar" and made a "dirnt, dirnt, dirnt" noise while pretending to pluck the strings.
