Scrub.
Thats the term we used way back in time when kids first entered Jr. High School (aka a noob in general gameing terms).
That part about people who do the same thing all the time and people who bitch about it was funny. If I play a CTF game I always lean towards being the defender...aka "camper" and always seem to piss off some self proclaimed leader....no matter that I never let the other side excape with our flag or have a 10/1 ratio.
