Egotistical Arrogant Bastards!
Conceited people and those overly so have always bothered me. The sad fact is that these people spend so much time boasting and giving themselves high-fives that they don't realize how pathetically insecure they really are. If you are truly good at something or smarter or prettier, you don't have to convince me or anyone else for that matter. I steer clear of these people because sadly even if they are chopped down to size, they always believe the failure as not their fault. To me this just takes too much work. Who gives a shit? I don't.
