So many are now familiar:
WASP = White Anglo Saxon Protestant
NIMBY = Not In My Back Yard
DINKY = Double-Income No Kids Yet
But now we (in UK) have
NIPPLE = Northern Isrish Professional Person Living in England
V-cUnt = Voting Conservative Until Next Time
OWL = Older Web Literate
Any good/stupid ones happening in your neck of the woods?
