What turns you off the quickest?

[Zennyboy]

people take the mick out of me, because if i try to think too fast i end up falling over my words, which is why i sucked a cussing matchs at school, im one to take my time, think things through, safe to say i got my grades, i got my qualifications and such so im happy, but i do hate being online and finding quick witty arrogant *insert profanity beeper here - beep beep beep beep* man it does get on my nerves and put me off those type of people very fast.
