Funk and filth.
Funk is life. It's the sweat from a hard day's work. It's mud on your clothes from playing outside with your children. It's the dirt under your nails from gardening. It's the glow of sex.
Filth is death. It's the dirt of laziness, buildup and neglect. It's the stink of poor hygiene, the leftover dust from housework ignored too long.
We all get funk every day. Wash yourself. Or not. That funk's just gonna turn to filth real quick. If you're okay with some filth, then don't worry about it. It'll help you weed out all the polite gentrified fucks you don't wanna be around anyway; they'll stay upwind of you. It's personal choice.
Personally, I choose to wash it off every couple of days. I love the funk but I hate the filth.
