Usage
What does nit mean? Nits are the eggs or young of small parasitic insects, most commonly lice. They are especially called this when they are attached to hair. Nit is the basis of the word nitpick. Nit is also used as an insult referring to a stupid person, though in this case it’s a shortening of the word nitwit, which may or may not be related. Example: Your scalp won’t be free of lice until you remove all the nits.

Origin of nit2
First recorded in 1590–1600; perhaps from nit 1 ( def. ); perhaps from nit(wit) ( def. )

Explanation
A nit is a louse egg. If your scalp is extra itchy, get someone (maybe even a "nitpicker" to check you for nits. There's no getting around the fact that nits are pretty gross — they're basically baby lice. Nits can be tricky to spot on an infested person's scalp, because they're smaller than a grain of rice and a very pale color. Colloquially, to "nit pick" is to find and criticize someone's faults, no matter how tiny they might be. Another, less disgusting kind of nit is a scientific term for an amount of light emitted.
