Idaho Spud Thumper
When one cooks a bake potato to perfection with all of the fixens ie: chives, pepper, cheese, bacon and instead of sour cream uses their splouge. Then the potato is served up to a lady while she is thumped from behind.
Instead of taking her out to dinner we stayed at my house and I served her up the ol Idaho Spud Thumper.
