Mediocity
Mat "Pookie" Swingle's favorite "word", which in fact isn't a word at all. It was just mediocrity misspelled on a Panda Express fortune cookie that Mat found when he was 12.
Mat showed me the fortune cookie paper while we were hanging out one day. It said, and I quote, " Be broke or be wealthy, but never accept mediocity."
