1. achieve sth, complete sth well
Well done, you really nailed it!
'Nailed it' is a popular colloquial expression which means 'to get it right' or 'to succeed'. It comes from the idiom 'to hit the nail on the head' meaning that accuracy was achieved. It is often used sarcastically, however, to mean the very opposite. It is usually used in popular media such as tutorial videos or on social media to compare the success of a project to a finished example shared by someone else. This is a very casual phrase you might use among friends or within your social circle. Expressions with a similar meaning include 'aced it', 'hit the nail on the head' and 'you killed it.'
