Moments of "Wow, I dun goofed"
Whiffing your flash tibbers when you play annie, and your initiation decides a teamfight
Ulting the full hp, cc based tank as Katarina
Deciding to fight over a pink ward when you see 1v3 and you think you were fed (but really just 2/6...that was embarassing)
Buying Luden's Echo, then realizing all your skills say "Physcial Damage" ._. woops
Thinking that Trinity Force passive stacks with Iceborn Gauntlet and Lich Bane (derp)
Trying to buy Ninja Tabi and Mercury Treads to defy Darius
You guys got any?
