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.

grammarape 

The very act of posting something on the Internet that absolutely ignores all rules regarding spelling, syntax, and punctuation. Grammarape will be the ultimate undoing of the Internet and will be what convinces alien life forms to completely bypass our planet as nothing more than an intergalactic truck stop.

Please note.. this is about GRAMMAR. Yes, the word looks like "Gramma Rape," but please understand that this has nothing to do with sexually violating your mother's mother.

"I'm pleased to see that you performed a heinous grammarape in that email to me."

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.
