In reference to a married or co-habitating couple, on parole refers to when one's spouse or partner is out of town, leaving the other person to temporarily live a pseudo-single life style, wasting time and money in an orgy of short-lived freedom. Often characterized by the person hanging out with his or her single friends, that have probably not been contacted in a long time. Also refered to as a jail break

every night this week!
(adj) Out of prison before the end of the sentence, but still required to report regularly to the authorities.
