no u

The ultimate comeback back, that is normally used when there is no other comebacks to be made. By using the comeback "no u", you instantly win the fight/argument, unless the opponent pulls out a reverse card, if this happens you just run, you run away as fast as you can.

Opponent: ur mum gayyy
You: no u

u/

u/ means username/ and it is used in Reddit and is well known in the Reddit community. People use u/ insert random name here to mention a random Redditor to tell them to get their butts onto a post or to show others who the person is. BE AWARE that when you mention somebody they can see what you commented that made them go onto the post

Anne: Hey Harry how do I mention a Redditor again I'm still new to this website, please help.

Harry: You just type u/ and then their Reddit names and there you go that's the dummy's guide to mentioning somebody on Reddit.

Anne: Did you just call me dumb?!

Harry: No...
