Edge Online's Gaming Lexicon
I just found this on Edge and thought that it aptly named some experiences that are immediately recognizable to anyone who games. I especially enjoy "Arenaitus" (the immersion breaking premonition of an impending bossfight), "Playacting" (actions taken in a singleplayer game that are 'in-character' and nonessential), "Killicious" (a weapon that is so satisfying that the player changes playstyle just to use it) and "Finger-Feat" (instinctive feats of skill that couldn't be repeated intentionally). These things needed to be named, so I hope they get incorporated into the greater cultural gaming dialogue.

I for one am going over to Cafe-Press to make myself a "Doak" shirt.
