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...

No U

No U is a way to reverse the action that somebody has done to you are said to you. Kinda like a Uno Reverse card?

Kate the thot said “I’m blocking you on my contacts!!”, so I said “No U”
