grammar Nazi
Someone who insists on correcting or criticizing others for errors in spelling, grammar, and syntax, especially to a pedantic or self-righteous degree. Potentially offensive due to its reference to the fascist National Socialist German Workers' Party, which was brought to power in 1933 under Adolf Hitler. It irritates me to no end when people use "good" as an adverb, but I try not to be a grammar Nazi about it. A: "What are you, a grammar Nazi?" B: "Hardly. Everyone knows you shouldn't use 'ain't' in a formal paper."
grammar police
Someone or a group of people who insist on correcting or criticizing others for errors in spelling, grammar, and syntax, especially to a pedantic or self-righteous degree. A: "What are you, the grammar police?" B: "Hardly. Everyone knows you shouldn't use 'ain't' in a formal paper." I don't mean to be the grammar police, but you shouldn't use a semicolon to introduce a list—that's the job of a colon. A: "It irritates me to no end when people use 'good' as an adverb." B: "Well, keep that to yourself, because no one likes a visit from the grammar police."
