Please use damn English you nub.
Done. Please note: Languages have capitals, slang is always either in quote marks or italics or indicated by apostrophes and you forgot your full stop.
Apostrophes are not the same thing as single quotation marks, and no, putting slang terms within quotation marks or typing them out in italics does not make any sense unless you are somehow referring to the word itself and/or want to take some distance from using the word.
Using slang terms is always kind of tricky. Whether a word is appropriate or not depends on the context and the level of formality. Seeing as the level of formality is pretty low here, and as most of the readers are probably familiar with the meaning of
nub, he did use the word acceptably.
