And then...
The Likes Everything No One Else Does Geek
This specimen is known to post very strange things(like cars, games, etc.) and tell everyone it's the best thing out there, beats everyone elses "old crap", and tells anyone who doesn't agree that "You, sir, are an arrogant ass!", or "Boy, who made you the all-knowing God?".
Plus:
The "Different" One
The kind that loves to tell everyone that they suck, everything they like sucks, their stuff sucks, and the world, in general, sucks. Why? Because they think they are sooooo much different, and the only things that DON'T suck, is THEIR personal stuff...because they can't get the other things, and want them, and since that is the case...well...it sucks...also, likes to call anyone who likes a particular item a "fanboy".
And even...
The Nitpicker
When engaged in a flamefest, this brain child loves to say "degrading" things such as "It's not spelled that way.", or "I wish I could get away with being as arrogant as you.", or, "You're stupid."
The Boaster
Favorite saying is usually "Yes, but mine is 100 more hp/mhz/mph/GB/whatever" or something along the general line. Everything he owns is better than everyone elses, and he can "prove" it...which never happens.
The Really Asshole-ish Asshole
A complex combonation of all of the above...
