weresmut 

Something that is generally normal that happens to transform into smut every full moon.

Terry: You're reading a smut book again??!
Sarah: GOD! It's just a weresmut book, and it's a full moon tonight! I swear it was a regular book ten minutes ago!

wereslut

Someone (usually a girl) who becomes excessively horny during a full moon, and spends the following 28 days regretting what she does that night.

Josh: Hey, are you still hooking up with Tracy?

Jake: Naw, she's a wereslut.

Josh: Oh, I guess you have to wait a few weeks before you can hit that again.

Wereslut

A person, usually a girl, who becomes indistinguishly slutty at a certain time of day, or on the weekend. They are most easily spotted in their usual habitat, anywhere that alcohol is being served in abundance.

Amber: "Look at that girl over there, she looked so nice when she came into the club, what happened??"

Kate: "She's a wereslut, normal during the day, whore at the club."
