vagina + vascillating = vagillating. When a PMS'ing woman is being an indecisive princess. Related to male condition of manstration but with indecision.
She says, "You're going out with your friends tonight, and I don't want to go out with your friends, but I want to hang out with you. Maybe I should go out with you. No, maybe you should just stay in with me. No, maybe I'll just stay here all by myself and watch Steel Magnolias on VHS."
I say, "I'm going out. Come with me if you want, but you'll have to stop vagillating."
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
