My thinking is that the aglet is a well known word these days, but if you were to poll a group, it would be mostly younger people who know what it is. Because of Phineas and Ferb.

I’m glad so many people responded and most people got it right! But, I’ll have to do a real poll to figure out if there’s any actual correlation here, and also account for the fact that people who know what it is were more likely to answer than those who don’t.
