In my experiences, women tend to be pretty filthy, at least in regards to their living areas...
Female apartments....

Especially if like two or three are living together....
fukking dirty plates laying around everywhere.
Toilet bowl, shower, and sink all fukked up. Get some comet you fukking bytch.
Trash cans filled to the brim.
fukking clothes just everywhere on the floor.
No dusting, or any evidence that they spray shyt down and wipe it off on a regular basis.
Knew some chicks that didn't own a vacuum cleaner. Like, they had been living in the apartment for like two years and simply never bought one...it was just whatever you could pick up off the carpet by hand and after that....
And it's a wrap if they have pets.
Women just don't give a fukk....
As far as their physical hygiene? Ehh...most people in the US bathe and brush pretty regularly. Most people are relatively clean.
