One who uses refined vocabulary, correct grammar, constantly finds themselves correcting grammar and spelling (in forums, chatrooms, tumblr, YouTube, etc.)

First, you have your mild GNs, they're much kinder and respectively tell you about your grammar/spelling that is incorrect.

Then there's your experienced GN, they're much harder on you and constantly browse through pages to reply to people who have terrible grammar and spelling form.

Finally, there's the hardcore GN, only they have earned the right to sPELL liKe thisss and still be refined, respected, not a asshat GN like most internet GN are. They usually reply with a simple correction and move on.
If people's verbal words could be seen like they were typed:
'omg your gay'
"What about my gay?"

randomanon101: lol that coment was so funny. your all so silly.
Grammar Nazi: *comment *you're

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.

People who forget that it's the comments section of a website on the Internet and not a school exam, Job application letter, or other type of formal document.

An attempt to gain back some ground when one is losing face on a forum.

A very similar term is Spelling nazi, one who does the same but srutinizes people for bad spelling. Or a mixture of both, spelling and grammar nazi.

Synonyms include Grammar police, GrammarCops,
'You grammar is astrocious'....Wow like I just wrote a paragraph and you're flagging me for bad grammar. Talk about completely missing the point, Grammar Nazi.

A grammar nazi is someone who does not have a life and only corrects your grammar. For example Jan havi.
Jan havi is such a grammar nazi!

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*

Someone that points out the most slightest grammar or spelling mistake. The most innocent of people can briefly turn into something so low called a grammar nazi. They evolve when insecurity in heated arguments arise when a fault with one of the opponents spelling or grammar must be pointed out as an utter write-off excuse. A grammar comeback isn't a diss or even an ownage on any sort of level to begin with despite how well placed it could be. It's one of the worst cop out excuses of a finish/settlement driven by people that make it even more pathetic when "umadbro?'s" (angry people) use it over "the internetz" (the internet). Just from the fact that society accepts improper grammar this day and age for example a movie that might be called "I spie with my little i" makes grammar comebacks an automatic backfire period.
User 1- "How can the next xbox go a blu-ray drive if Sony is Microsofts compititor idiot?"

User 2- "*facepalm* so the xbox original must be reading off your moms cooch from hand-me-downs that used the same thing. How did that work? Your grammar is just as bad as how badly you missed the "e" in competitor.

User 1- Umadbro? I feel pretty owned um..but...since you turned into a grammar nazi at the end I don't feel so owned anymore as you pretty much voided EVERYTHING for being so low.
