Nyub is like a better version of word noob or newb. It has been invented by skiry to describe stupidity of some people on discord. It can mean anything thats bad. Its plural is not nyubs but nyubz. It can be used as a verb in the same way as get rekt and then you say get nyubd. Also a very important thing about this word is that it cannot be used against skiry himself(this includes reversing it with a reverse card).

here is an example
fascist 1: skiry you retarded commie idiot!
skiry: nyub
fascist 2: skiry can you say anything except nyub?
skiry: nyubz...
fascist 1: really?
skiry: get nyubd
