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.

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

A captious individual who cannot resist the urge to correct a spelling and/or grammar mistake even in informal settings. After pointing out the linguistic shortcomings in others, a Grammar Nazi feels a strange sense of twisted and unconstructive intelligentsia delight.

In reality, they are making someone else feel bad for no reason and unintentionally implying that their "superior" grammar skills are all they have to show for a wasted liberal arts education.

While proper grammar usage is all well and good, a Grammar Nazi cavils even insignificant errors in English to somehow win an argument. Of course, rather than being genuinely persuasive in an argument, pointing out English errors is a weak attack only on the typist's credibility and never has any bearing on the underlying premises and assertions therein.

In other words, this is simply a disguised ad hominem argument which intelligent and logical people disregard.

Still, one should strive to spell and use words properly, but arrogant and unsolicited advice is not a very persuasive way to teach English.
