When you see something that's really nerdy(like a museum exhibit that most people would find ridiculously boring) and you get all excited and then as your excitement peaks you start to squeal and act quite like you're orgasming.
Hey did you see that exhibit of the old WWII planes?

Yeah, I totally had a nerdgasm

When one surrounded with something or someone extremely nerdy or geeky.
Nerd 1: "So Eugene, in Star Wars episode 4 at precisely 1:53:45.6 what do you think OB 1 should have done?"

Nerd 2: " Well I don't know, let's have a Star Wars slumber party with Bob and Frances and make a list of reasons!!"

Derives from the word orgasm.

When someone has experienced just too much nerdiness at one time, they are saidto have a nerdgasm. The person usually goes into a state of shock and can't speak for up to 1 hour. Never distured a someone who as recently nerdgasmed because the person is prone to just spurt out random nerdy things that regular people could never comprehend.
Person one: Dude, the PS3 is going to use blu-ray discs, imagine the texture file quality!!!

Person two:*nergasm*!!!

Have been shown to occur during: lectures over human variation; lectures over cranial morphometrics; study sessions; book readings; debates or discussions over philosophy, literature, evolution, books, research, experiments, thesis, dissertations, etc.; library activities; the act of being big spoon to a freshly printed warm article.

Have been shown to occur (yet, are not limited to) if and when: bow ties are present; guys are reading book; a discussion about literature and schizophrenia become an act of foreplay; the smell of old books is in the air; glasses are worn by an individual; a great bookstore is found; one of your ten lifetime academic boners occurs.
Checkout that professor wearing the bow tie. And back to my problem about the lecture on evolution and human variation, religion is not negatively correlated with rationality. Furthermore, in regards to the lecture over cranial morphometrics, the increased scientific validity and reliability that would result from the methodological standardization proposed for the analysis of cranial morphometrics to estimate ancestry is brilliant. Oh my goodness, checkout the guy reading a book. My apologies, I may have just had multiple nerdgasms.
