A band of boys that think that they are all that. they also believe that they are true rockstars, when in reality they are a bunch of butt-fucking faggots (Hence the name " NAKED Brothers Band" )that everyone hates. Also, Since none of the them have hit pueberty, it sounds like the chick is the lead singer.
