That's the home run point: you might not have to pay it back. That is exactly why the debt or credit card analogy doesn't hold. An uncovered call is exactly the correct metaphor. This isn't even high finance we're talking about, this is fundamental options stuff. I'm not sure I understand the resistance to using the uncovered call terminology as opposed to the highly innaccurate (but more Main Street comprehensible) "debt" analogy. Debt (aside from bankruptcy ALWAYS has to be repaid. Yet we all know that technical debt doesn't always have to be repaid. Debt is a terribly imprecise way of thinking about it.
