Campers R' us
Doesnt matter if its bush, mountain, building, or shadow, the camper will always find ways to annoy even the most skilled player.
Time to beat: Never as a campers craving is never satisfied, even with a 100% accuracy rating
Little Kids
Kids of age 13 or under with really squeaky voices that abuse the mic and always swear because they're imitating some of the older players, and it makes them seem "cool".
Time to beat: ALWAYS. And if you're on their team, follow them, wait for someone to kill them, and proceed to teabagging.
The Adaptable Noob:
-Gets killed by a manta. Says mantas are for noobs.
-Gets killed by flak. Says flak cannon is for noobs.
-Gets killed by an avril. Guess what? avrils are for noobs.
etc
Time to beat: The very second they kill with whatever they were whining about. Then its suddenly "pro".
All or Nothing
These players are remorseless and browse servers looking for easy prey, they play like there life depends on it, never giving an inch to an opponent regardless of skill level or point spread. They play only when they are at the top of their game and play to be at the top of their game, anything less is unacceptable.
They use terms like "GG" after a match as some kind of sarcastic remark instead of an honest opinion, using it as a cloak of good sportsmanship when deep down they know it wasnt a good game. Saying "nice try" or "nice shot" to an opponent shows weakness so is avoided at all cost, infact you may never see these gamers type anything aside from "GG". Although they can occasionally be seen spamming taunts during matches their all or nothing approach to gaming means you'll see them often at the end of the match, when they are in practise ofcoarse.
The You might have won, but I'm still better
Gamers who fixate on winning at the cost of everyone's fun - including their own, and going by the "you only won because (...)" mentality. This includes all of the usual stuff like spam, hax, [x weapon] whore, and the cheap tactic that always wins but nobody uses because we're all gentlemens following the unwritten rules.
The Bandwagoners
They think such-and-such game is good or bad just because their friends/a website or mag/popularity says so.
Time to beat: Easily in most games, varies in their game(s) of choice.
The Oracles
They are right about a game no matter what kind of arguement you present and their lack of one. They deny you with ease and sometimes will try to change the subject.
Time to beat: Never in an arguement as they simply toss yours aside, easily in game as they clearly have no experience with games and are often a part of the Halo Players Coalition.
Guitar Hero/Rock Band Whore
They will mock you for playing anything less than expert.
But then again it is so much fun to mock them when they are stumped with a real guitar or drum set. I challenged my friend to playing real drums with me down at [No Advertising!]. Poor guy could not even keep a steady beat, but gloated how he mastered expert rock band drums!
He gave me a ton of excuses but the matter of the fact was that he sucked and being a pro at rock band did not make him a real musician.
"So, it's defeat for you, is it? Someday I must meet a similar fate..."
