NW Twee 

Proper noun: Hampstead. An area of North West London covered by postcode area NW3. Hampstead is populated largely by moneyed liberals, champagne socialists and aged ex-hippies which results in taste and style choices that are annoyingly twee. NW3 + twee = NW Twee.
Pronounced 'enn double you twee'.

"Tarquin and I are torn between renaming him 'Life' and 'Cactus'. It needs to be something that expresses his masculinity yet - bugger! He's puked his yak cheese and aniseed brûlé all over my pashmina shawl."
"Bloody hell Saskya, you're so NW Twee!"
