Used to name the sluttiest slutty mc'slut-slut. Generally a slutface will be very good friends with a whorebag. It is common knowledge that any slutface would make the perfect girlfriend to a well hung man, or animal.
The ridiculous amount of make-up a girl wears before a big event, like a date or a dance, usually used to boost confidence or to attract men.
I was wondering why all the girl's faces looked like they were baked on, then I remembered that Winter Formal was right around the corner. Slutfaces are so gross.
