first order

When you're a bit late to the game and haven't quite caught up with the latest trend. You're not on the cutting edge but you're not totally clueless either.

Person A: Have you heard about 'x' social media app? I've already amassed 100k+ followers.

Person B: I think I read about it but haven't downloaded it yet.
Person A: You're so first order.
