A weak person that always gets stepped on. All talk and no action. A non-vocal vocalist. Someone who will recieve a Dirty sanchez willingly and then complain to their peers about it later. Spineless fuck,supreme follower with alot of mouth. Coward of the highest order.

That's why he oftens gets a dirty [brooke}.
