Geekation is the act of being a geek even though you know its geeky. This therefore makes your geekiness seem rebellious and somewhat cool.
Man, Steve's our quarterback and captain of the chess club? That dudes gettin his geekation on!
A relaxing time away from work, where nothing is done during time off except playing on the computer, logging in Facebook or Twitter time, playing video games, texting, playing with any new gadgets.
I will miss everyone at my Genius job at the Apple store, but I will be taking a Geekation for the next 5 days, doing nothing but vegging in front of my computer and playing video games.
