The all in one excuse, whine, and expression of disgust from a top notch slacker. The moan of an extremely lazy person when confronted with a request to do work.
I asked Nick to help me clean up the mess he made. All I heard him say was, "Come on, maaaaaan, I gotta godo somethingright now."
MAAAAAneh is a feeling or way of describing something boring/meaningless/or just something you have no interest in. As a feeling it means to be bored unsure of what to do/say you feel slighty out of place lost even, much like the word BLEH.
It can also be used in a conversation to show disinterest or you cant think of what to say back in an argument.
