word to describe someone who doesn't know how to take care of themselves. Either their hair is nappy, their pits stink, their clothes are dirty with stains, or all of the above; A nasty person able to attract gnats.
This dude came in today lookin' real gnatty. He stank like booty, his teeth looked like he brushed them with butter, and his hair looked like he just got outta bed.
