Meaning a book that comes up for sale over and over and over. Not speculative books as in, "Hey, Jerry Bruckheimer announced a Hansi, The Girl Who Loved The Swastika movie so I better buy all the copies I can than unload that sh*t right before the film comes out so I'm not left holding a Hot Potato" but Hot Potato like an undisputed key that comes up for sale, a lot. Maybe it's CPRed again and again or whatever. But the book comes up for sale a lot so it's, rightly or wrongly, thought to have baggage.
Anyways, how long after a sale before the book loses its identity as a Hot Potato book?
