The night before Valentines day when you take out the person you're sleeping with behind your husband/wife/girlfriend/boyfriend's back see jump off. Because you can't take them out on Valentine's Day, so you have to take them out the night before. Jump-off night activities include renting a hotel room by the hour and buying your Boo slutty crotch-less panties.
My boyfriend refused to take me out for Valentine's Day. When I badgered him for a month straight about why he finally confessed that him and wife of five years have had long-standing plans on Valentines Day at their favorite restaurant and he could only take me out the night before. That's when I realized that not only that I was his jump-off night lay.
