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 nerdgasm is when something very nerdy and awesome occurs, and you are overwhelmed with a feeling of awesomeness and nerdiness.
The scene in Avengers: Age of Ultron when all of the infinity stones are seen and everything connects may cause a nerdgasm. It may also happen after the credits of a Marvel Cinematic Universe film, especially at the end of Iron Man or either of the Avengers films.
