a hall pass is used to refer an agreement between a couple that they can have sex outside of their relationship, generally on a one-off basis. It is usually a celebrity or someone you would never see again
A one off thing doesn’t make sense. You’re either built that way or not. Either monogamous, or you’re polly. So no I don’t agree with it unless you’re both built that way and knew that from the get go that it will happen. :)
