I am watching a movie, "slender man" and I came across a phrase that i have no idea of its meaning:( Someone please help meee It's "faces on milk cartons" I know its literal meaning but i don't know what it means in this situation. The situation is that a group of girls saw the slender man and one of the girls is missing. so one girl searched about the slender man and another incidents of missing children or abduction. She is talking about what she searched to another girl.
