The ONLY known technique that is able to free you from the almost-inescapable insult, known as, "ur mom gay lol."

How to use this dreadful counter:

1. Bait your (already dead) opponent into using the one hit one kill insult, "ur mom gay lol."

2. Smile! You've already won. Use the "no u" comeback.

3. Watch your opponent die a horrible death. Don't let children watch, as the violence is too much for young minds.
Fortnite player: Hey uhh, wanna play some Fortnite bro?
You: Uhh, dude? Miss me with that gay shit.
Fortnite player: Hah! Ur mom gay lol!
*You smile cruelly, as it's just too easy.*
You: no u... lol
*Fortnite player dies an indescribably violent, bloody death.*

The fucking best comeback anyone could say. It is impossible to say things after that apart from no u back.

The ultimate reply to someone when they try to insult you.
Man 1: Fuck you
Man 2: no u
Man 2: no u
Man 1: You're a insignificant piece of garbage with nothing to live for, no one in the world will ever care for you. Your existence is a lie. You think that you are intelligent but in reality you are someone who is hurt, mistaken and FUCKING USELESS. You attempt to hide the truth that you're scared, but we all know you are scared. You want to reply something else instead, you decide to just say the same phrase over and over again, you have no skill or a life. You just spend your life on the internet and act all high and mighty on there; but as soon as you go into the real world, you'll just be like everyone else. Useless.
Man 2: n o u

The end all to any argument. Used when one either has no intelligent argument left, wants to try and use "no u" as an intelligent argument, or want to piss someone off. Most effective after one has been insulted.
