Starting from the stroke of midnight, an hour from where a girl (or guy) can be as sexually promiscuous as they desire without judgement of their actions being cast
Girl: what time is it?

Guy1: *looking at watch* it's slut o'clock!

Girl: sweet, time to go get me schlongs o'plenty!

Guy2: woah, what a skank!

Guy1: hey, retract that comment kind sir! For if one had looked at their watch they would see that it is midnight and thus slut o'clock!

Guy2: I do apologise, go about your business fair maiden and good day to you sir!
