The Extraverted Nerd is a young teenage nerd (almost Always Male), who dresses and behaves very awkwardly. Unlike the usual stereotypical nerd, he's completely oblivious to his nerdy nature or at least acts it, and is a Casanova Wannabe who goes after girls without any fear of rejection. In fact, he doesn't take "no" for an answer. He usually serves as the stooge to the main character.
Many nerd characters in shows with laugh tracks are like this. The TV Genius is a less annoying example. Although, whether an Extraverted Nerd has actual high intelligence or merely a high opinion of himself varies.
Compare/contrast Dumber Than They Look, when a character with stereotypically "smart" appearance is not actually smart.
- Ox Ford in Soul Eater is a serious nerd, but also a badass fighter, which often makes him overlook his own nerdiness and think he's as cool as the cool kids.
- Mike Wazowski from Monsters University is a bookworm who's not afraid to flaunt his smarts over the Jerk Jocks.
- Tombo in Kiki's Delivery Service; despite being a nerd about engineering and wearing thick coke-bottle glasses, he's still very outgoing and is shown to have a lot of friends.
- In Turning Red, Mei is quite an outspoken nerd, and has a very self-confident, if a bit conceited, attitude where she "wears what she wants and says what she wants 24/7, 365". However, this is only how she acts when she's away from her mother and her stifling expectations.
- McLovin in Superbad. He starts out that way but by the end of the movie he has sex with a girl and stages himself getting arrested to appear like a Badass.
- Booger from Revenge of the Nerds. (Using a somewhat broader definition of "nerd" than you see in more recent media — he's more of a slob — but the non-nerd characters in the movie do consider him a nerd.) Has few (no) social graces, and is a total extravert who utterly fails to understand why people find him repulsive, unlike the more vanilla nerds of the rest of the cast.
- Superstar has a rare female example, Mary Katherine Gallagher, a totally unselfconscious extravert and show-off who really has no clue that she's a total nerd.
- Molly in The Poison Apples is a huge nerd (her favourite book is the Oxford English Dictionary) and proud of it. She isn't shy, tends to take over conversations when no one asks her to, and is less hung up on her Friendless Background than her new friend Alice (who at least had some friends, if not close ones).
- Buffy the Vampire Slayer: Wesley Wyndam-Pryce is described in the script of his debut episode as "thinks he's Sean Connery when he's pretty much George Lazenby."
- Family Matters: Steve Urkel. Steve actually does know he's a nerd, he's just usually proud of it or at least puts on a brave face when others pick on him. Only Laura is finally able to shame him into trying to change, which leads to his genetically altered clone. Later on in the series, when she does agree to date him he starts dressing slightly less nerdy but is still just as proud to be one. By the end of the series, Laura has finally accepted Steve for who he is and even fallen in love with him.
- Saved by the Bell: Samuel "Screech" Powers. Also pretty much anyone in the school classed as a "nerd" is actively portrayed as if they are an entire race all to themselves to be derided by our heroes. The worst part was the "heroes" were usually considered as being rather nice to the nerds.
- Carlton Banks from The Fresh Prince of Bel-Air mostly qualifies for this, but he does get his chances from time to time. His short stature does not really help much.
- Irwin "Skippy" Handelman in Family Ties. Unusual in that Skippy was even less intelligent than Mallory Keaton.
- Cookie in Ned's Declassified School Survival Guide.
- Rare female example: Quinn in Zoey 101.
- Ron Yuma in Naturally, Sadie.
- Howard Wolowitz from The Big Bang Theory. Howard actually knows he's a nerd, but chooses to ignore this and act like he's cool in the hopes that people (especially women) will be fooled. He fits this trope so well he could perfectly be the Trope Codifier for younger viewers.
- Rico from Hannah Montana.
- Lawrence "Larry" Tudgeman III (a.k.a. "Tudge") from Lizzie McGuire, also a subversion, as he was apparently a nice, normal guy outside school.
- Penelope Taynt in The Amanda Show, please. Also a stalker, who may or may not have been a Stalker with a Crush.
- Reality show example: Richard Rubin on the first season of Beauty and the Geek. (Most of the other "geeks" were closer to Cool Loser and Endearingly Dorky.)
- The Latest Buzz: Cody Herman (who calls himself "the Her Man").
- Moss in The IT Crowd, although his character is arguably more aware of his nerdiness than most of the characters attributed to this trope.
- Robbie from Victorious. Sikowitz even tells him "Way to go, Urkel!" in Locked Up.
- Noel in Frasier appears to be so convinced that Roz wants him that in the finale, when she kisses him out of excitement of her new promotion and Gil asks him if it was worth the wait, Noel assumes Gil was talking to Roz.
- Will from The Inbetweeners knows that he is unpopular and socially awkward by the standards of the normal society, but he hates these standards which result in that half the time, he tries to become one of the popular guys, and the other half, he insists/implies that his notion of social norms is much better than actual norms. Either way, this trait will often result in him being a quite good example of this trope.
- Milton in Kickin' It reaches an interesting point in terms of Stock Costume Traits. Dylan Riley Snyder specifically mentioned that Milton'll unbutton his top shirt button more often in season 3 just as One Direction's made the buttoned-up look trendy.
- Farkle Minkus in Girl Meets World, although he has a BSOD when a bully shoves his nerdiness in his face. Season Two toned him down considerably. In this, Farkle is a Generation Xerox of his father, Stuart Minkus from Boy Meets World.
- Arnold Rimmer in Red Dwarf is older than the usual examples, but his utterly bewildered that other people don't share his enthusiasm for Hammond organ music ("Not even Reggie Wilson's Lift Music Classics?") and aren't interested in his Risk war stories. He also has a firm belief in the power of his terrible chat-up lines, even though he has had one confirmed romantic encounter, with a woman who was possibly concussed and calling him Norman.
- Adam Goldberg fits this trope: a bespectacled nerd with a passion for all things to do with theatre, film, TV, and performing.
- The singer in Five Iron Frenzy's song "You Can't Handle This".
- The main character in the music video for "Weird Al" Yankovic's "White and Nerdy". Note that while in the chorus he seems to admit that he's nerdy (or at the very least, he acknowledges that other people see him this way), his Boastful Rap in the verses indicate that he thinks he's real hot stuff. He's apparently extroverted enough to invite gangsters to go bowling with him, but so far he's had no takers.
- John Flansburgh of They Might Be Giants has been regarded as having a nerdy personality and is shown to be the more sociable of the two Johns.
- Jameson (or Jamison) Winger, in the World Wrestling Federation, who was originally a nerdy, socially-challenged Ed McMahon-style sidekick for the short-lived "Bobby Heenan Show" segment of "WWF Prime Time Wrestling". He later became a recurring character (in the same mold) on WWF television, and even served as a sidekick for the Bushwhackers tag team. Bears a striking resemblance to Andy Kindler (of Everybody Loves Raymond fame), although Kindler swears it was not him and has even gone as far as to claim it was another Andy Kindler. Which is strange, because Jameson was portrayed by an actor named John DiGiacomo.
- The Gorgeous Ladies of Wrestling (GLOW) had Zelda the Nerd.
- Neptune Vasilias from RWBY is an odd inversion. He initially comes off as a cool lady's man, but he's implied to be afraid of heights (and a crippling fear of water as of Season 3), can't dance, and is an intellectual. According to Episode 7 of Volume 2, he actively works at constantly being seen as cool to make up for his failings.
- Flash in Boy Meets Boy starts out as an incredibly nerdy Manchild. Then he decides he wants to date and finds someone to teach him about women. And he picks... Fox. Results are predictable.
- Out at Home has Eddie, the nerdy nine-year-old with a massive crush on seventeen-year-old Penny, who he has tried to seduce several times. The results are, well, expected.
- Ed from Paranatural is confident in his nerdiness and has been seen hanging out with various classmates. Summed up when Johnny learns that he's never bullied Ed:
Johnny: I haven't? But... you're a nerd.
Ed: Well yeah, but, like, the fun outgoing kind with lots of friends.
- Whateley Universe character Peeper, of Superhero School Whateley Academy. He hits on every hot girl on campus, to the point of out-and-out harassment. He thinks he's awesome. He's the best-known broadcaster on WARS (the Whateley Area Radio Station) and he broadcasts the school Combat Finals. Girls avoid him like the plague, especially once word gets around that his only superpower lets him look through people's clothing.
- Zaboo in The Guild. He's technically not a teenager, but he is a Manchild who begins the series still living with his overbearing mother.
- Pan Pizza of RebelTaxi is a self-proclaimed "cringelord," and tends to make a lot of jokes about female cartoon, comic, or video game characters he'd like to screw.
- Upchuck in Daria, though considering that the stars of the show are all fairly nerdy outcasts in some way, his appearance is less jarring.
- Tina Belcher in Bob's Burgers is a female example. She is socially awkward and wears thick Nerd Glasses, but doesn't let that slow her down.
Tina: I'm Tina. I like horses, music, and boys. Hi, boys, I'm Tina.
- Gandhi in Clone High affects an over-the-top "cool guy" persona, but at best he's the class clown. Of the popular clique, Cleopatra ignores him whenever possible and JFK only notices him when he attempts to make him over (to look and act more like JFK, of course) to win a bet in homage to She's All That.
- Tucker Foley from Danny Phantom as the quote above classifies in full. He even looks like Urkel!
- The Simpsons:
- In "The Last Temptation of Homer," Bart is prescribed thick corrective glasses, special orthopedic shoes, a scalp cream that mats his hair down into a dorky center-part, and a throat spray that makes him (temporarily) sound like Jerry Lewis. He is confused why his normal (this episode) outgoing personality is met with derision until he catches his reflection in Milhouse's glasses and gasps, "I'm a nerd!" Milhouse seems afflicted with this too as he sees himself in Bart's glasses and gasps, "So am I!" (In other episodes, Milhouse seems perfectly cognizant of what a dork he is.)
- Martin Prince is even nerdier and even less aware of it than Milhouse. In "Bart Gets an F", Bart has to break it to him that he's not popular and everyone regards him as a joke, which he doesn't believe until Bart demonstrates by tripping him up to summon The Freelance Shame Squad.
Martin: But my—my speed with numbers, my years of service as a hall monitor, my prize-winning dioramas? These things mean nothing to them?
Bart: Perhaps another demonstration. [shoves him over, to mass laughter]
- Total Drama:
- Cody. According to his official online bio, he fails to recognize his own geekiness because he legitimately is cooler than any of his friends (who make up the Albert Einstein Fan Club at his preppy private school).
- Harold is even dorkier. Interestingly, he seems to acquire the "lady's man" aspect of the trope not long after Cody loses it (or at least, sets it solely on Gwen).
- Recess: Vince's older brother is pretty much a blatant reference to Urkel. In an interesting twist, though, he knows he's a geek — it's jockish Vince who's in the dark.
- In Over the Garden Wall, Jason Funderberker. His confident attitude sets him up as a Foil for Wirt, who's about half as dorky but twice as anxious about it.
- Bobby Hill from King of the Hill is a fat and awkward preteen who has a lot of nerdy interests and hobbies as well as being In Touch with His Feminine Side but he is also very charismatic and engages in a lot of social activities and school functions, has attended and hosted parties, and has gone out with several girls. This is Played for Drama in some aspects as his father Hank's regularly shown to be disappointed that Bobby turned out this way instead of as a Lovable Jock that Hank himself was as a teenager. Despite that Bobby is shown to be more or less as friendly and likable as Hank was a kid, with Hank being too hung up on semantics to recognize Bobby's more capable than he gives him credit.
