A term used to describe those who go out of their way to look and act a certain way in order to fit a social stereo type. An example would be the ever popular "hipster".
The term could also be used to describe a group of people attempting to start a new sub-culture or counter-culture of their own. The pioneers of a new bandwagon trend.
Sure, you could join the "bandwagoneers" or, you could just find your own style.
