For some reason, geeks like to make jokes that geeks actually have sexual arousal about their geek interests. Not sex or fetishes, this is about the latest technology or something like that. Basically, it's the geek factor that is turning them on. If the thought of Wonder Woman fighting Storm turns someone on because it would be an awesome comic, and not because it's two hot chicks fighting, you have this trope.
This also doesn't count if a guy just has raging hormones and gets erections at anything, nor does it count if it's merely Squee! or And the Fandom Rejoiced. There has to be implications of sexual arousal.
This can happen even when Nerds Are Virgins.

- Code Prime - R1: Rebellion: Lloyd's reaction to seeing Cybertronians in their robot forms is...interesting, to say the least.
- Yellow Overdrive Power Ranger Ronny seemed to get quite hot and bothered when she saw the zords her team were going to be driving. The fans, of course, latched on to her "zordgasm", and soon put her in a Cargo Ship (with drills, after she had a similar reaction to the Drill Blaster in a later episode).
- Stephen Fry has a nerdgasm in this video after spotting a Tesla Roadster in traffic and hearing how big of a touchscreen the new Model S will have in the dash.

- Parodied on an episode of Saturday Night Live with a fake commercial for a sex chat line featuring women dressed as different geek icons (including Princess Leia, Uhura, and Galadriel) who speak only in references to their respective works.

- Kryten in Red Dwarf is programmed to enjoy cleaning. When he's turned human in "DNA", this translates to him getting an erection while browsing a vacuum cleaner catalogue.
- A PG version of this trope occurs in FoxTrot with Jason ogling a computer ad in a magazine the way an older boy would ogle a magazine centerfold. Peter's done the same thing with a guitar magazine.
- Jason and Marcus have both ogled a National Geographic with no-holds barred, fully detailed diagrams of the Apollo 11 lunar lander.
- Naked Snake/Big Boss from Metal Gear Solid 3: Snake Eater had one when EVA gives him the .45. He's got a woman with her boobs out in front of him, but he's staring at that gun and gushing over it like he might just try and have sex with it!

- In Disgaea 3, Comedic Sociopath Mao has a tendency to do this whenever he witnesses something particularly evil. His reaction is complete with labored breathing and drooling. (It's probably worth mentioning that Mao embodies a number of stereotypes of RPG gamers.)
- Makoto Nanaya of BlazBlue literally does this in Tager's Continuum Shift joke ending, when Tager transforms into a giant gold-plated Humongous Mecha in order to fight a giant robot version of resident Cat Girl Taokaka. Don't ask.
Makoto: "Oh... My... GOD! Commander Kokonoe, that is so awesome! No, seriously, I'm getting a tingly sensation in my naughty bits... Please, can I have control? Please? Pretty please!?"
