No U is a way to reverse the action that somebody has done to you are said to you. Kinda like a Uno Reverse card?

'No u' is a simple comeback given by simple people. People will use this term when they can't think of a decent comeback fast enough and will usually think that they have won an argument by finishing up with a classic 'no u'. They haven't won the argument. They just made themselves look like a a thick nonce.
