This is how we said it at my (five) elementary schools in California, c. 1978-1985.
If some girl at recess was on MY monkey bar, or stole my Members Only jacket from the Lost & Found, or popped my water weenie, my best friend called her out like this and there could be a fight after school: “MOTHER FUCKER TITTY SUCKER TWO BALL BITCH! insert name, e.g. TINA MAMA’s IN THE KITCHEN COOKING RED HOT SHIT!”
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.
