no stupid questions is to allow you to ask things you might be embarrassed about, like things you "should" know already as an adult, mildly taboo topics that people generally aren't willing to talk about in polite company, or questions that might come charged with a bit of controversy. I'm sure that doesn't cover all the cases, but that's the general vibe I get.

Ask: what's the velocity of a swallow carrying a coconut? I can't find an answer after a few days of research and it's really hard to catch one to attach.

nostupidquestions: Is anybody else attracted to sparrows?

nostupidquestions: what's a chafing dish for?
