The anti-honeymoon. Rather than being a holiday taken in the aftermath of one's wedding, a cunnymoon is a trip taken by a man recently made single, where his sole aim is to get some carnal, commitment free action.
Did you hear Jason booked a holiday?
Yeah, he's going on a cunnymoon after the break-up with Sarah.
I took a three week cunnymoon in Pathos, forgot all about the lying, cheating bitch that broke my heart.
