A Hard Pass is a consensual conjugal visit at a correctional facility between non-married or non-committed consenting adults who previously have little or no contact with each other. The hard pass is initiated by the non-incarerated party, typically drawn in by a picture of the jailed person.
When Brad saw the new story that Christina had been arrested trying to shoplift a bottle of whiskey, he went up to the jail and made a HARD PASS. A good time was had by all. It is different from being SHAWSHANKED because - one party is not in jail, and both parties are consenting adults.
