Someone who gently corrects your grammar.

Unlike a grammar nazi, who wishes to exterminate the errors in your ways (and possibly you along with them!), every grammar mountie is as calm and reassuring as their namesake, the beloved and gentle members of the Royal Canadian Mounted Police.
Turns out that I am dating a grammar mountie! She doesn't even mention it when I misuse a word in a sentence, she'll just use that word appropriately later and then smootch me when I recognize her tactful lesson. We will have many, well adjusted children who will win local spelling bees.

Todd became very angry when his American friends spelled "centre" incorrectly. Todd is a Grammar Mounty.
