Derivative of "Hoovertown" and "Hoover Blanket". It is a makeshift cooler made of a cardboard box lined with newspaper.

Unlike the other "Hoover" words, this isn't a sign of poverty as much as convenience (when you don't want to take an empty cooler home).
What's in the box, Paul?
Lunch: it's a hoover cooler.
