nonplussed
To put at a loss as to what to think, say, or do; bewilder.
A state of perplexity, confusion, or bewilderment.
So then I’m plussed most of the time?
CORRECTION!
I mistakenly wrote above that Mitt Romney’s grandfather was a polygamist. THat’s not true. His GREAT-GRANDFATHER was a polygamist. HIs grandfather was not.
George Romney would have never been elected dog catcher had he been born of a polygamist marriage. Those rules don’t apply to the current president, however.
Hopefully, though you might also be whelmed, sheveled, gruntled or raveled.
