A fashionable hair cut where one side of the head is shaved to the scalp, leaving the rest intact and respectable. The term is derived from the description of a mullet as being 'business in the front, party in the back'. It allows the person to be deemed respectable from one side, and rebellious from the other.
Since my housemate's boyfriend got a party side, he scares old women in the street.
