A person on the Internet that uses proper spelling and grammar. They usually dwell on forums or other social websites and correct the grammar/spelling of, or insult those who have improper grammar or spelling.

The Grammar Nazi will be hated by the person targeted by "He who spells". The "victim" will usually resort to useless insults.

It is a sophisticated form of trolling. The end result is serving the duty of the Grammar Nazi, and causing the idiot to be enraged.
(Assuming this takes place on YouTube. GN = Grammar Nazi.)

Person: "dat vid was sooo tight man u r a genius. da vid iz funny cuz its tru"

GN: "Excuse me. Did you take elementary school English classes? It seems that your sentence has many spelling and punctuation mistakes.

Person: "*response or private message* hey man wat da hell iz wrong with u? just cuz u no how 2 spell doesnt make u ne smarter. u r probably a virgin or gay. hahaha. u cant even get gurlz. deres no reason 2 b a grammer nazi"

GN: "Well, it might not make me smarter, but it definitely makes you dumber. Don't even get me started on the mistakes in that response."

*to self* "Success."

Known to be quite the buzzkills, often digressing from the main point of discussion to fulfill their need to correct grammatical errors and typos, mostly in a condescending tone. However, their rising population suggests that they are charming the pants off each other, their loins warmed by the idea of impeccable grammar, while pissing everyone else off.
Here, you can see, a Grammar Nazi in his natural habitat, mating with his lover in the widely popular Oxford Comma position.

Definition one: Somebody whose either losing an argument and needs to create a diversion.

Definition Two: Somebody who has the analytical and decrypting skills of an autistic 6 year old who cannot recognize a routinely based word if it even has a liiitle typo or misplacement that anybody with a brain would so easily recognize. This person is often impossible to communicate with due to the need to spell every single thing perfectly or else they will get confused due to their poor description and analytical skills. Everything taught to them after grade 1 fades out of their mind in no more than 2 minutes. Talking to them is like talking to a wall.
Example one:
Reasonable Human Being 1: wtf you got your dick stuck in a bench and cut it off to escape from it?! ur stupid bro! rlly stupid!
Grammar Nazi : Learn to spell before you call me stupid!
Reasonable Human Being 1: Aha! So you tried to change the topic to grammar because there's no way you can provide a reasonable response to what I have said! You sir are a typicl Grammar Nazi!
Grammar Nazi: Typical*
Reasonable Human Being: Shut up you have no dick. Literally you have no dick you cut it off and this is why you're resorting to being a Grammar Nazi!
*Grammar Nazi blocks the Comprehensible Human being because he/she has no good comebacks*

Example two:

Comprehensible Human Being: why is it that you stare blankly into space for 18 hours a day while chewing on your shirt?
Grammar Nazi: What the hell do you even speak English? Your grammar is atrocious!
Comprehensible Human Being: Any autistic child would be able to recognize what I have just typed....
Grammar Nazi: Oh my god! You put 4 dots! I have no idea what you're trying to say! Learn to speak English please!
Comprehensible Human Being: If your mother dyed her hair black would you still recognize her?
Grammar Nazi: No of course not! Who would be able to recognize such an enormous change?
Comprehensible Human Being: Ah OK I think it's settled. You're just plain retarded.
*Grammar Nazi is chewing shirt while bug eyed*
Comprehensible Human Being: I rest my case.

A person who has mastered the art of speaking the English language. They are best known for going on social media and constantly correcting the incorrect usage of other users, and are almost universally hated by everyone. An occasional correction does not signify a Grammar Nazi, that title is earned after months of corrections.

KEEP IN MIND: Many people who are corrected by a Grammar Nazi really need the public shame because they've put too many poorly-written statuses on their social media accounts, and the Grammar Nazi should be hailed as a hero. If the person in question is clearly not a native English speaker, then the Grammar Nazi is the villain
Guy: Grammar Nazis mean us no harm. There simply helping us hone our grammar skills.
Grammar Nazi: *They're
Guy: My mistake. Thank you.

Someone who is so educated, they are so inclined to pick out every damn grammatical mistake you make in common conversation, texting, and websites. They make you feel uneducated. Just like Adolf Hitler and the Nazis, they want to control every facet of your grammar and sentence structure. They say "Oh, I'm just trying to help you through constructive criticism.", when they obviously are just calling out mistakes for personal gain.
Teenage Girl: "Oh my ged sharon, i was at the mall the other day and i bumped into sharyl!"
Grammar Nazi: "You misspelled god, didn't capitalize 2 names, and didn't capitalize 2 'I's."
Teenage Girl: "stupid grammer Nazi"
Grammar Nazi: "You misspelled grammar, and didn't capitalize the word beginning the sentence."
Teenage Girl: *clicks out of chatroom because Grammar Nazi won't stop his shit*

An idiot.
1) Someone who is too stupid to think of a reasoned response to any argument so resorts to attacking someone's grammar and spelling instead.

2) Someone who has failed to grasp that forums are not in fact English essays. Language has always varied according to context, just as we use different types of words in a job interview compared to with our mates.

3) Usually in English forums monolingual native English speakers who utterly FAIL do to the fact that 60% of times they are criticizing someone who is using English as a second language at a far higher standard than the grammar nazi would ever be able to use a second language themselves. 30% of remaining cases the person they are talking to is native English but is dyslexic or 10 years younger. And all 100% of times the person being criticized has much better things to do with their time than correct their every spelling mistake. In either case the grammar nazi fails!

4) Someone unable to figure out the difference between intelligence and correct grammar and spelling.
1) erm.. I don't understand. Brain hurt. Damn why do I have to be so stupid? Oh well- let's just insult his grammar and I'll feel intelligent again.

2)Grammar Nazi"You didn't cite your references or write a proper conclusion- you can get an F for that essay"
Normal Person"erm... Lol it's not an essay its a forum post!!!"
Grammar Nazi"eh? I'm confused? Where am I? Who am I?"

3)Grammar Nazi "You use 'their' not 'there' DUMBASS!"
Janic : Sorry my English isn't up to your standards. My native language is Czech so maybe we should switch to using Czech. As you suggest you are more intelligent than me due to my lack of English logically you must be able to speak fluent Czech as well."
Grammar Nazi "oh... erm... errr" FAIL

4)Grammar Nazi "Your arguments are invalid as you lack the intelligence to use apostrophes correctly"
Philosopher: "Hmmm... Intelligence... what really IS intelligence? In our culture we have learnt to.... (intelligent discussion of intelligence)
(Grammar Nazi's head explodes at this point)
