"It really grinds my gears when someone rushes me and then shows up late. Grinds my gears means something really annoys you, usually in a slow, nagging way that keeps looping in your head. It's a mechanical metaphor, like a gearbox being chewed up, and it got a massive boost from Family Guy, where Peter says it whenever he's wound up. Works for petty stuff and bigger injustices. Where does it come from? It comes from the older image of machine gears grinding when they don't mesh right, all noise, friction, and ugly resistance. The wording was already around in English before pop culture got a hold of it, but Family Guy blasted it into everyday slang with Peter Griffin's reoccurring 'what really grinds my gears' bit."
