TITS OR GTFO
From lurkmore wiki
TITS OR GTFO is commonly seen on /b/ or /s/ in response to pictures of girls that are not showing naked breasts (or nudity in general), indicating that they can choose to show them or GTFO (get the fuck out). Often posted with an image depicting a multiple choice test with two boxes, "Tits" and "GTFO" labeled "The choice is yours." The same image is also sometimes posted with the "GTFO" box already checked, for subjects found to be boring or unattractive.
