grammazi 

A person that cruises forums looking for bad grammar and belittles the user of said bad grammar. Combination of two words-grammar and nazi.

Yo, I got schooled by some grammazi today for not using proper sentence structure.

Grammatical Pedantry Syndrome 

Grammatical (or grammar) pedantry syndrome is an illness or a form of obsessive-compulsive disorder where someone has a compulsive desire to correct any grammatical errors one has made and is obsessed with taking this peculiar, constant, and vexatious (from the target's perspective) action.

"Me and mark ate cookies!"
"You mean, 'Mark and I ate cookies!'"
"Stop it!"
"Sorry, I have Grammatical Pedantry Syndrome."

Grammatical Pedantry Syndrome 

A fake syndrome created in a joke blog by Dennis Baron of the University of Illinois. Many people were fooled by Baron, as the article heavily uses scientific jargon, making it appear like a legitimate piece of scientific literature, but the actual text includes a litany of linguistic jokes and signs that it is actually a hoax. Also, anyone with a basic understanding of OCD would be able to tell that the purported symptoms of "GPS" are dissimilar to actual OCD symptoms; OCD is an anxiety disorder defined by intrusive thoughts and repetitive behaviors, not a need for order or structure.

Grammatical Pedantry Syndrome is a load of baloney, however I do have Memetic Veracity Syndrome; that is, the need to correct false information (particularly contained in memes) on the internet.

Grammatical Math 

When the words you are saying do not add up correctly to make sense.

"I was the only one to help set up for the party today and I did everything" "Didn't Mark, Jim and Pam help you set up? That grammatical math don't add up."
