W.A.S.P.

White Anglo-Saxon Protestant Descendants of colonial-era immigrants from the British Isles--especially England, but also from Wales and Scotland (irrespective of the fact that Scots and Welsh people are predominantly descended from Celts, not descendants of Angles and Saxons)--who belonged to the Presbyterian, Congregationalist, and Episcopalian (Anglican) denominations of Protestantism. The term is redundant because all Anglo-Saxons are white.
