No U

Typically used by 13 year olds as a shitty comeback. Almost never works. Also used alongside the uno reverse card meme

Kid 1: yo mama so fat I'm standing on her right now
Kid 2: no u
Kid 1: oh shit he just pulled a pro gamer move

No u

The most powerful substance in the world that can reflect anything
The substance that is needed to make the infamous ‘UNO reverse card’

No U

This is used in situations where if the person you have insulted cannot think of a good comeback, they use the phrase, no u.
