The nerd equivalent of adrenaline, a nerdrenaline rush is when a nerd, geek, or dork engages in an activity that stimulates them in ways that only nerds truly appreciate.
Nerd #1: Dude, the ending of Star Wars Episode VI always gives me a huge nerdrenaline rush.
Nerd #2: Yeah, same with me. That, and the Discovery Channel.
When a nerd gets revenge on someone who would otherwise be considered not a nerd. e.g, When a nerd humiliates someone on the internet for screwing them over.
He totally got nerdvenge on that dude who sold him the brokenlaptop.
Nerdvana came to an end when Kurt Cobain, Kurt Cobang, Kurt Cobaing or whatever that loser called himself used a shotgun to blast his head apart and make a big gross mess. (By the way, what has four legs and works at McDonald's? Nerdvana!)
