A person that has a Grammatical Pedantry Syndrome. Part-time editor and proofreader for English or Tagalog Novels.

You don't know what Grammatical Pedantry Syndrome means? Well, let me just explain it here so that you won't waste your time searching for it using google. 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.

Peculiar - unusual
Constant - occurring continuously over a period of time
Vexatious - (Vexatious on the floor!) causing or tending to cause annoyance, frustration, or worry

Yes, for short I'm that person that gets easily triggered by grammatical errors or misspellings.
