A person who corrects your grammar purely out of genuine concern for your apparent ignorance, and to help stop the bastardization and ultimate death of the English language.
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."
this sentence is grammatically correct but it's wordy and hard to read is an AD and yet we made it famous. as soon as you say it or it comes up on youtube. everyone will say it
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.
"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."
