Definition of "Wasp"

Purists like to confine Wasps to descendants of the British Isles; less exacting analysts are willing to throw in Scandinavians, Netherlanders and Germans. At the narrowest, Wasps form a select band of well-heeled, well-descended members of the Eastern Establishment; at the widest, they include Okies and Snopeses, "Holy Rollers" and hillbillies.
