Hair dictionary: "splitting hairs"
What most people think it means: taking a hair and splitting it in two.
What it really means: getting too bogged down in tiny details. It’s generally used to describe someone very meticulous, or too picky. Basically someone who gets worked up over nothing. The phrase is thought to have originated in the 17th century, with the Oxford English dictionary listing the phrase "cutting the hair", which paints an even clearer idea of giving something a whole lot of effort, for not a great outcome.
