metaphor describing a person balding at the top of the scalp. (“Man that guy totally became a stadium in the past year”) The speaker was using a stadium as a reference to particular type of balding pattern, i.e. centered at the top. In a stadium spectators look on to the big ‘empty’ playing field in the center. So in a person balding from the top, the hair are analogous to spectators on the outside and there is an empty field in the center.
