When a girl (or guy) wears too much make-up. Making it obvious that she/he spent 40 minutes applying her BB cream, MAC concealer, "natural" Cover Girl foundation, and translucent powder finish. Followed by dark/noticeable eyeshadow and "ultra volume" mascara. Making everyone shocked and disturbed when it's time to take the make-up off, exposing their terrible complexion and TRUE appearance.
Guy 1: DUDE, LOOK AT THAT CHICK!
Guy 2: Ew, she's a Powder Face dude, that's gross.
