Where to begin..... lol
People that go SLOWLY through the self checkout isles at stores. I go to those isles because I can ring my stuff up, bag it, and pay atleast twice as fast as the cashier. If your slower than the cashiers, you should be required to go to a cashier. Usually there is someone watching the self check isles, and I think this person should be given the authority to deny someone self-checkout privlidges.
People that ride my ass on the highway when I'm in a slower lane. I'm a bit of a lead foot as it is.. so someone that rides my ass is going WAY OVER the designated speed limit. It just pisses me off and I respond by slowing down. I saw a license plater holder that reads "I See Dumb People... Reading This Sign." Its not all that clever but I always laugh. (I saw it in a parking lot btw)
People who make loose sushi rolls. Just fucken wrong. Sushi is such a beautiful, wonderful thing to eat..
One uppers. "Thats nothing! I" blah blah blah blah blah
