Oooh, I like this topic. I may have to set up camp here.
For me, my number one is people who like to look down on others. I'm talking the kind who like to rub credentials in your face, talking like they're the gift to this planet or something.
I'm sorry that I only have an associates degree. Clearly I'm nowhere near as intelligent as you are with your bachelor's/master's/doctorate's/whatever. No my degree is not from some Ivy league school. I'm sorry that there is no chance that you and I could possibly hold an intelligent conversation because you're going to use so many words (quite inaccurately often times I might add) and I just won't understand.

really get to me. Get off your high horse already. Grrr; lol
