promposal

It's called a promposal.  It's the name for when someone asks someone else to the prom.  Lately they've gotten pretty extravagant.  Some kids even spend more on the promposal than they have on the prom.  I would guess it's worth it when it works.  But when it doesn't, I'm sure it can really feel like a disaster.

Proms have become incredibly extravagant. If the dresses aren't expensive enough, there's also the limo, the flowers, and now even the way in which you ask has to be a production. They're called "prom-posals," and they've gotten pretty creative over time.
