"some of the Waspier types"

WASP stands for White Anglo-Saxon Protestant, an informal and frequently derogatory term for an American social elite, generally of British (or more generally Northern European) descent with a Protestant background. WASPs are often associated with private school educations (leading to Ivy League universities) and inherited wealth. The first reported usage was by political scientist Andrew Hacker in 1957, but by this time it was already common terminology among sociologists.
