Armoury humper

A person or mammal who, in a game of Natural-Selection (a half-life mod) persistently sits in front of the armoury getting more ammo.

Whilst doing this he/she becomes incapable of even basic human functions such as speech, hearing or killing the alien which is in the process of killing his/her team-mates.

They are widely hated by most other NS players, who have far better things to do, like beg the commander for a shotgun.
