A shortened version of the phrase "I know what you mean".
This is even shorter than the term "nah mean", which is shortened for the phrase "Know what I mean?".
Even though both terms are similar, they are not often confused. Humans are able to determine if a question is asked by the tone. The term "n' mean" is so short that a different tone is used.
Mike: I just stubbed my big toe. I hate it when that happens. Nah mean?
Amber: N' mean.
