Nostalgia Sack: A condition of psychological captivity held over you by the past works of certain artists or pop-culture properties that makes it impossible for you to dislike anything they do in later years, to such an extent that you would stop supporting them.
EG. "Green Day have sucked since 2004, but they know it doesn't matter, they've got you by the nostalgia sack. All they have to do is promise to play tracks off of "Dookie" and you'll continue to help them buy new Yachts while excusing their awful fucking music.
