It means that you got something exactly right. Like the phrase ';You hit the nail on the head'; - your aim was perfect and you accomplished exactly what was attempted/expected.
Two usages are possible:


1. 'He uttered a lie and I nailed it': Here it would mean to me, that the lie has been exposed. (Slang.)


2. Nailed it is used in the sense that something has been fixed or fitted perfectly, as has been pointed out in the earlier answers.
';nailed it'; comes from the saying, ';you hit the nail on the head.'; hitting a nail perfectly on its head with a hammer is tricky to do - without hurting yourself, messing up your project, or bending the nail. so when someone says ';you hit the nail right on the head,'; it means that you said or did something EXACTLY and precisely right. ';nailed it'; is a shorter way of saying ';yes, you got the point, you are correct, you have the best answer,'; etc.
