When a woman verbally attacks a man (because he's a man) instead of addressing his argument.
Shelly: 2 + 2 = 5.
John: No, Shelly. 2 + 2 = 4
Shelly: Stop mansplaining to me, John! That's just like a man. You misogynist.
John: You're using ad womanem attacks, Shelly.
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.
FRIEND A: "Did you just take a stealthie of me?"
FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
