I, too, thought it was "verkelmpt", but after seeing some proof sent to me by another, much more famous board member, I now know the truth...
The correct spelling is either "farklempt" or "ferklempt".
Of course, I will continue to use my incorrect spelling, as I have no little Yiddish-speaking grandmother to hit me with a spatula if I'm wrong.
I starred in a short film called
Magnetic Personality. Check it out!
