Zefyr Moment

When you see someone you want to talk to irl, but for whatever reason, you can't. They could be on the phone, with a crowd or they might just look like they're not in the mood to chat at that moment. Regardless of the reason, it's a Zefyr Moment.

Guy: I saw another girl wearing that vintage jacket you love!

Girl: OMG! Tell me you asked her where she got it?! You know I've been searching for weeks.

Guy: Nah... Zefyr Moment. She hopped on the bus before I could talk to her.
