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 

"When you need a comeback from 2003."
No u is basically the Uno Reverse card of a convo.
When this is said whatever the person did and/or said to you is instantly on them instead.
Use this wisely, or the sake of humanity is at stake.

Guy 1: Hey, Guy 2, you suck!
Guy 2: No u
Guy 1: Now I suck

No u 

"No u," or in proper English, "No, you." This is the ultimate end all to any argument. Commonly used to reflect a statement, usually an insult, back onto the one who used said insult. Affirming that the insult is more suitable to the one saying the insult, rather than the one receiving it.

-Often used as a response to the phrase kys

Guy1: "You embicile. There is absolutely no truth to what you have just said, at all. You must have been dropped on your head as a baby, as I see no way that an intelligent human could possibly believe that."
Guy2: "no u"
(argument concluded, as there is no way to come back from this)

Guy1: "kys"
Guy2: "no u"
