>>piss elegant
Is it a Brit expression?

May be, Auntie Entity (recently revisited Mad Max 3 ), but it's not a frequently-used term in my experience. More well-used amongst Australasians, I believe -- but they can speak for themselves.

It means OTT (over the top) or taking-the-piss elegant. Going out for a pizza in evening dress, perhaps. Trying to look stylish, but ending up looking twee, possibly even pathetic. Of course you could have piss elegant objects as well -- or rather objets.


P.S. Greetings, pugrant!
