The people who go to every damn car show every weekend in your area and get mad when they don't win a trophy, particularly the people that tell you how much money they spent "building" their car, and get pissy because they didn't win a trophy.
An extension of this is people who complain about judging. Perfect example, some asshole at a car show that my daughter and I went to last year complained loudly when he didn't get a trophy. The show was at a church and the youth group were the judges. And he made a stink about it. Get the f$$k over yourself!
