Schnitzel boot

Let's see if I can contribute to launching what is as far as I can see at this point in time a one-user slang term.
Hannah, from our office:

Oh – schnitzel boot is the term I use to describe the women who are alumni from my school, all dress the same, talk the same, send their kids to the same school, and do lots of pilates – oh and a BMW 4wd is mandatory for entry into the schnitzel boot club.

It's very sayable.
