An explosive, often verbal, sensation caused by a mind-blowing occurrence relating to nerdy material. A strong enough nerdgasm can lead to violent spasms similar to those of a seizure.

An overexposure to an electronic item worthy of awe, or jumble of code-scripting and multimedia representing in a fucking awesome playable interface (aka a fucking awesome video game). One in this overexposure usually Splurges uncontrolably over anything within a 10-20 foot radius(occassionally blue???). A state of shock arrests the splurger's abuility to do anything from anywhere between 5 minutes to three months. If one tries to avoid a nerdgasm they are a n00b and should be pwned imediately by someone totally 1337.

A rhetorical debate or discussion resulting in mind-blowing excitement and the sudden and increasing release of endorphins into the body (much like an orgasm) immediately following a series of intellectual word-f$&*ing. The example below actually happened - this mind-screw was completely and spontaneously improvised! ...not to mention that the fact it was an analogy about sex (one guy and three girls)... using ICE CREAM! lol. Such a nerdgasm!
Male: You’re on my mind.
Female: Why?
M: Neapolitan ice cream. I have a redhead, a brunette, and what color is your hair?
F: HA! Blonde! Nice! Well, this vanilla just might melt away behind the chocolate and strawberry before you can scoop me up. No offense!
M: You might be surprised at how fulfilled ice cream feels when the right spoon is used
F: Oic
M: ...because w/o that person to enjoy the ice cream with that perfect spoon, would that ice cream be able to fulfill its purpose of being savored... truly enjoyed by the senses?
F: But how do you know you have the right spoon for this vanilla? I mean, there are many different spoons and MANY kinds of ice cream! And different flavors should not have their individual eccentricities neglected when selecting the proper spoon.
M: LMAO agreed! The only way to tell is to try.
F: Hmmm- I wouldn't say the ONLY way to know is to try. One could get to know what needs the ice cream may have.
M: Ice cream should be tasted, not heard! How does one get to know what needs the ice cream has?
F: By checking out the cover, then the label; find out what kind of ice cream, if it was like others you'd had before, if it was NUTS, or fruity, or some sort of rocky road to it. Then you'd refine your spoon choice with experience.
**Pause**
F: Whew... I gotta admit, that was fun!
M: Are you smiling?
F: Completely! That was such a NERDGASM I had right there! What about you? Where's your head?
M: That NERDGASM was shared! :D
