Cockiness
Cockiness (noun) 1. offensive boldness and assertiveness. This is one of my most disdained traits in a person, besides prevarication (rudeness is also a problem). If a person is as good as he or she claims, why boast? If one is truly THAT GOOD, then "shut the fuck up," and let your actions prove your worth. Sadly, win or lose, the loser is 'the cock,' or the cocky person for lack of self- confidence, and the obnoxious and blatant cover-up of their insecurities.
