A lower form of nerd, that even the standard nerds laugh at, insult and beat up.
A group of nerds come out of a Star Trek Convention, and see a short, skinny geek with coke-bottle glasses and hip-waders sitting on the sidewalk, caressing his autographed William Shatner poster.
When you're discussing something geeky very intensely.
When you know a lot of information about something unusual, usually nerdy, and express it with great enthusiasm.
Bruce: Batman never killed his villains until Robin died, which is the only reason why people began to call him 'The Dark Knight'. And in the series 'The Dark Knight Returns', Robin was a girl after Jason died.
Wayne: Dude, relax. I only said I was excited for The Dark Knight.
Bruce: Sorry, I was nerding out for a minute there.
Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.
