nonplussed

Often misused as meaning unfazed, but actually means bewildered.

English majors are nonplussed about how "nonplussed" has, over time, become so misused.

Shuckadoff

A word that has no definition so when you call someone a shuckadoff no one gets hurt

Bob: i farted
You: Quit being such a shuckadoff Bob

realpolitik

See also: the novel "Mating" by Norman Rush. There is a scene where the ambiguity of the definition, and its proper pronunciation, are used to great effect.

See above example--literary.
