(n) A male version of the dreaded "bikini-spider." These unfortunate social-faux-paus are caused by a total lack of twigs-and-berries grooming. Also known as "out of control" male bush, brusters should never be sported in front of your boys or potential ladies.
Dude, I am never sharing a locker with Mike again...we are changing for a quick game of lacrosse at the club, and I fuckin have to look at his brusters for 4 minutes. They even show through his gay shorts. Fuck that guy.
