Certain words or phrases, and possibly certain people that use them, irritate the shit out of me. Things like "tinkle" "potty" "up and at em" "tushy" just piss me off, for no apparent reason.
I can't stand people who complain about not being able to eat while they drive. Its a burrito not a lobster, you don't need both hands to drive unless your on a mountain road with a stick shift. Also, the dillweeds that complain about how hard it is to drive a uhaul. What the hell, its interstate, what the hell. Or the dbags that can't even maintain the speed limit, the same people who slam on their brakes when they see a policeman even though they're going 25 in a 35.
I've noticed that most, granted not all, people from certain areas or nationalities have really irritating habits. But I probably irritate other people to so...
