Learn English – Soft or more euphemistic way of saying “suffer”

I think this comes from old-fashioned pay phones (or any other vending-type machine, like a drugstore gumball machine), where sometimes you'd put the money in and it'd get stuck, so you'd have to try various strategies (generally consisting of variations on "hit the dang thing") until the coin would finally get dislodged and drop, allowing you to make your call (or get your candy). The metaphorical meaning is thus to understand a particular bit of information after repeated failure. To use another metaphor, it's to finally get that lightbulb to go off.
