The afk = absent for whatever reason, he is but a free kill and officially 'not a threat'.
The camper = lazy, he'll just camp in a corner and keep shooting, occasionally clipping people across the map.
The farmer = using the good old bot 1 for whatever reasons, he may or may not be banned soon.
The guest = always fun company with his skills and carefree demeanour.
The lagger = whether intentional or not, he has mad teleportation skills and boasts occasional immortality. Everybody hates him!
The noob = brand new to the map, he moves incredibly slowly and gets killed by everybody...
The pro = boasting an impressive kdr, he'll constantly moan about SP or write paragraphs about something which happened in-game 8 years ago.
The salt = are his enemies too good? Too bad? Too laggy? He'll resort to democracy via the kick option or setting a certain ping. Thankfully he always fails.
The voter = does not really care for kills but he must get those few hundred kills in order to fulfill his map making hobby.
