NN means "no-name" in hvh speak. For example when you kill someone better than you, you would say: "LOL get 1d retarded nn ur mad."

NN is usually used by a bunch of nns calling each other nns.

It is also used by 5 queue ragers in non prime. For example in a 1v5 mm hvh when they kill you:

Rager 1: 1 nn
Rager 2: bad refund
Rager 3: lol cant be a real p2c
Rager 4: 11111111
Rager 5: uid? uid? uid?

You: Are you guys retarded or do you not realize you are this thing called losing.

short for "no need" this is trading slang in the game Diablo 2 for I do not require any of the items you have shown me, a "ta" after indicates that the quality of said items is high and that you simply do not require them , a nn noob means that you think the items are poor
"nn ta" or "nn noob"
