This is somewhat unfair. If you already think someone's a blowhard, and you want to take the wind out of their sails, go for it, but a lot of people who have some legitimate expertise won't have a definition at their fingertips.
Or if they do know, you'll tip them off that you don't think much of them.
Or they might give a legitimate answer that differs from your own flawed understanding. In which case you're just a jerk to judge them by it.
Reiterating what I said to ChristianKI, it's not about seeing whether the person has a "correct answer", but whether they're already aware it's a non-trivial question.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
