The females, opposite version for " bros before hoes. " It refers to woman who ditches her friends at the drop of a dime to hang out or spend time with a man. Most of the time the man is just a flavor of the week, and the girl is pretty wack, or a straight slut that just needs to be rode hard and put away wet again.
I was supposed to hang out with Jill, but she straight ditched me for that guy she met yesterday. She's all about DUDESBEFORESNOODS.
