Put that in your pipe and smoke it!
i'm sure some of you out there have had expeiriences with people who think they are all that, but those people obviously don't always win. so, recall a time when someone was cocky, bragged a lot or was just plain rude in some sort of competition, and either you and/or your team made them eat their words.
i myself just played an online game against someone of the cocky braggy and rude nature, things looked grim for me until he made a stupid mistake and i turned the tables around. and to think he said that i should have surrendered because i was going to lose anyways (not to mention how he kept saying how immensly smart he was up until he made his crucial error).
