Another way of saying 'person', though noonches normally refers to the self. Often a way to define a slightly mischievous yet personable individual.
When I was a shady little noonches in college, I sold a little weed. I had one girl walk into my apartment with a mutual friend and look me in the eyes and tell me she should get some free weed just for hanging out and having tits. It felt good to see her turn red and walk out in a huff as I doubled over in laughter. The sad part is I'm sure she completely expected it because other morons would do that.
