Specifically, I am not about to start saying these are the guys I don't like because I have had quite alot of luck playing with nice folks.
Sometimes I don't enjoy listening to someone speak, I don't enjoy what is coming out of their mouths etc. but I only get irritated when
A. Someone leeches terribly and you don't know them (see know them, not know OF them).
B. Starts yelling because "we are dying". It's so not important. It is a game. 
AND Slightly C) I don't think I am at the point where I couldn't use advice about something but feel free to keep your comments on "how to play" a charecter unless someone asks. Otherwise you seem like a know it all.
But, I follow up with that comment, isn't that life? There will be some people you like, and some people you don't. If your not gelling with the party and so long as they aren't dicks - you finish the round and you leave. Don't be a dick and you may make a friend or two.
Kill them with kindness... and possibly bees.
Kind bees?
