Nerd vs. Geek vs. Dork

One of the most wonderful things about the English Language is the sheer number of words. With all sorts of synonyms for basic concepts, each word is nuanced, allowing for a very tight definition. Given that, there are so many insults, but too often are poorly understood.
     The Nerd vs. Geek vs. Dork divide is one of the deepest. Within these three words are three different concepts that everybody understands, but are frequently expressed with the wrong word. I'm here to set the record straight:
     Nerd-A person of great intelligence, but almost always in an academic field. Nobody would ever call a mechanic or a carpenter a nerd; One would call a medieval history enthusiast, a chemical physicist, an abstract mathematics devotee, and especially a computer wizard etc. The heavy implication of this practical/theoretical field of interest divide is that the nerd, in their love and interested in their field, limits their social interaction and people skill. The term nerd can to some people become a term of endearment, emphasizing their love of academics. Most important, a nerd MUST by knowledgeable, socially inept usually, but not required.
     Geek-The word originally referred to a bizarre circus performer that did things like biting the head off of a live chicken (to paraphrase "Hey Arnold," "Why do they call us geeks? None of us to that, except for Eugene" "And it was only that one time!") This is where we find the divide in Nerd vs. Geek. A geek does not need to be intelligent in an academic sense, rather the geek is usually more extroverted than the nerd, although not necessary any more socially conscious. The defining feature of the geek is the dedication to a facet of geek culture. Comic books, video games, anime/manga, obscure movies, star trek and other sci fi, fantasy fiction, role-playing games, Magic the Gathering, music (these then bleeds into the hipster), Jane Austin novels, and so on and so forth. Geek culture is something that exists in a post-modern age of irony, self-awareness, and the meeting of high and low culture.
     Dork-As of the time of writing, some controversy arose over the trailer to the film "The Dilemma," staring the doughy 6'5'' leading man Vince Vaugn, who makes a comment stating "Electric cars are gay." Beyond any question of whether this is homophobic, the more accurate term would be "dorky." Dorkiness includes the worst of both the nerd and the geek. The dork is not necessarily as intelligent as the nerd, and does not have the sort of ironic, self-depreciate humor of the geek, or the collective culture that comes along with a geek's interests; the dork fails to be trendy, misunderstanding all that is cool. At its root, the dork is the image of your parents, a generation behind, and blissfully ignorant of the various fashion and cultural reference faux pas being committed. The dork is the guy in high school that wears a boy scout uniform unironically (no offense to troopers out there;) the dork is the person that wears flag t-shirts when it's not the fourth of July; the dork gets a bowl cut; the dork gets a comb-over; the dork wears birth control goggles; the nerd reads Dostoevsky and Proust; the dork wears socks with sandals; the geek attends anime conventions; the geek grows their hair like a graduate student; the nerd attempts to explain those math formulas where you prove that 0=1; the nerd is Rivers Cuomo, Steve Jobs; the geek is the japanophile girl at the back of your class, mc chris, Kevin Smith; the dork is the aesthetic of Christian broadcasting channels, the father that refers to his pants as "slacks," and anybody that unironically grows a mustache (except Frieda, she's OK.)
