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 u²

The only combination of letters and numbers known to man that can beat "no u". Absolutely unexpected and so much more deadly than "no u".

Person 1: Ur mom gay lol
Person 2: No u
Person 1: No u²
Person 2: Dies in severe agony*
