Grammar Fan 

Fan of grammar. It's their name so capitalize it. That's their not there. I would start it with "and" ,but that's incorrect. That I needs to be capitalized by the way. Btw is incorrect.

You: lol look at that grammar fan.
Grammar Fan: Laugh out loud. Look at that grammar fan! (That's exclamative.)

Grammarian 

A funny little word that you may hear your english teacher may use to imply that s/he is religious in regard to grammar. I've always taken it to mean that your grammar will be corrected without remorse.

My english teacher swears she's a devout Grammarian.

grammarfag 

Someone who consistently uses grammar in all aspects of their posts or comments on Internet websites or games, particularly in areas where the main focus with communication is on speed and messages that are 'short and sweet'. These people often present themselves as elitist and often criticise and attack others who do not use the same amount of correct spelling and punctuation as they do. Grammarfags often tend to dismiss comments by others as incomprehensible if the comment does not contain full correct spelling and punctuation.

Guy 1: man that guy is such a grammarfag, who spends more time typing than shooting on an first-person shooter??
Guy 2: Whoa. What was that? I only speak English.

on an online forum
Guy 1: Okay guys, post some positive feedback for me!
Guy 2: gr8 work but wut i think u shud do is...
Guy 1: I'm going to ignore that comment because it I can't read it. Please have some human decency and use grammar for once.

Grammarian 

A grammarian is a person who believes that they have some type of mastery over the English language. Most times, they are misguided in this belief and come across as an asshole. The grammarian is related (by marriage, not blood) to the grammar nazi.

"I am a grammarian and have studied the ancient languages from Latin to Romulan, thusly, I have quite the command over the English language and a period does not go at the end of a sentence."
