You are one of Two Gamers on a Couch, enthralled by the latest noisy console game. As you furiously punish the controller old potato chips fly from your shirt, illuminated briefly by the glow of the screen before disappearing into the darkness of the room around you. You feel the sweet victory over your rival drawing near. As you are about to deliver the final blow, a mysterious figure steps between you and the television. Who could it be? Oh, it's just your extremely hot female roommate trying to get you to do something other than play video games. Whatever, you will unpause the game after you pretend to listen to what she says.
This girl is the Nerd Nanny, and how she winds up living with a bunch of lazy guys is a mystery. Even more amazing is the fact that the guys never seem to notice how frickin hot she is, unless some story-driving UST is needed. She is constantly trying to motivate the Non Action Guys to do anything, sometimes even to pay attention to her, but they usually won't have any of it. Fortunately for our male castmembers, she almost never leaves them for a different housing situation, because if she did — well, who would want to watch a show without hot chicks in it? Am I Right??
Note the guys don't always have to be nerds. Any reason to be couch-ridden also works (e.g. drugs, laziness, etc.).
This character is popular in webcomics and sitcoms, but is present in other genres as well. The Smurfette Principle is also a driving factor.

- Genderflipped in Princess Jellyfish. Cross Dresser Kuranosuke frequently visits the "Sisterhood," a group of androphobic otaku women.
- Played with in Genshiken. Otaku-hating Saki dates Kohsaka and plays this trope straight to some extent in the early episodes, but she mellows when it becomes clear that her controlling and abrasive approach isn't doing anyone any favors. The gender ratio also evens out after otakus Ohno and (reluctantly) Oguie are added to the cast, and after Ohno becomes club president the club becomes majority-female by a wide margin, so the usual gender dynamics are less of a factor as time goes on.
- Kristen Bell's character in Fanboys. Averted in that she's a fangirl herself, but she seems much more on the ball than all of the title fanboys.
- Averted in Grandma's Boy (2006). The Chick is something of a professional Nerd Nanny, its her job to get video games which are behind on development finished on time (it helps that all the nerdy testers want to impress her so they stop goofing around and work diligently). But it turns out to be an aversion when she reveals she also smokes pot, drinks, and even plays video games as well as they do.
- Sydney White, being based on Snow White and the Seven Dwarves, has this with the eponymous character, who becomes the Nerd Nanny to seven dorky boys.
- Donna or Jackie from That '70s Show.
- Penny from The Big Bang Theory, though she lives across the hall and simply likes the company and Leonard. Although we do see why they hang out with each other, as the guys, most especially Leonard and Sheldon help her out with her problems when she's experiencing them and she helps them get a lot less bullied than they normally still are. Another difference is that they do do things without her coaxing, and she does hers without theirs, but usually in their own social circles and what they try to get from the other party is a crossing of boundaries.
- Sheldon is the only one who's truly oblivious to her attractiveness, so it's not the straightest example of the trope. However, even when Leonard starts an off and on relationship with her, he's still easily distracted by comic books/Star Trek conventions/video games/whatever other nerdish pastime the others are getting up to.
- Subverted by Jen from The IT Crowd. She's hired to be the IT team's HR manager, but it soon becomes clear that while she doesn't share Roy and Moss' "nerdy" interests, she's not really any more functional than they are. On the other hand, they definitely need her to function; on one occasion when she's away from the office, the IT department devolves into complete insanity within one day.
- In a later season we see her office full of cute Anime characters, hanging out with nerds has influenced her to become nerdy but in a totally different way.
- Lilah from Ctrl+Alt+Del. However, she's a gamer herself and actually makes a living off of it, and even understands if Ethan needed to do something gaming related. On the other hand, any time she needs him to stop acting like an overgrown Manchild...
- Gender-swapped in Questionable Content with gamer-otaku Marigold and "regular guy" Angus.
