Flickr user chinese_fashion has posted a list enumerating 90 varieties of bitches. "My friend's cousin found this on the floor of a 3rd-grade classroom at a DC charter school," the person writes. See all of the bitches, from "stingy bitches" to "staring in your face bitches" here. (Suspiciously absent: List-making bitches.)

Tip from Mary, who is not a bitch.
