A person that looks sloppy. Their hair is so greasy that it looks like someone poured Crisco on their head. They haven't washed their clothes in so long that their blue jeans are a gross shade of green. Their teeth always have left over food in them.

A person that takes hella bad short cuts when putting together their outfit. Their clothes looks so wrinkled that people assume it was pulled out of the dirty laundry. Nothing matches, they'll wear check board shorts with a polka dot t-shirt.

AND, their hair is always nappy!
