Explaining NFTs on a First Date Without Sounding Like a Know-It-All

So I’m heading out on a first date soon, and I’m trying to figure out how to bring up NFTs in a way that’s relatable and not too heavy. I want to share a bit about what I do without coming across as pretentious or diving into jargon. Maybe something like comparing it to collecting unique digital art or having a special ticket to an online event? How would you break it down casually if you were in my shoes? I’d love to hear how others might approach this what’s worked for you when explaining niche interests in a lighthearted way?
