A BM starter kit is a set of clothing that young and uprising frat stars buy to begin living the frat life style. It was started by a young pike pledge and consists of polka dot bowties, chubbies, southern tide button downs, and ray bans. Oh and don't forget the sperry top siders.
A BM starter kit is any Rushie's clothing that is trying to become a pledge.
