Clit Cover 

The act of making up excuses to protect yourself from sexual intercourse by the man who wants to fuck you. This is not to be confused with a cock block.

Guy: Sooo, you wanna get out of here and go back to my place?
Girl: Yeeaah, uhhm, actually Im really tired and need to catch up on the last season of 90210 but thanks.....
Guy: This smells like a clit cover to me.
