using German word ought to get spelling right
A short google confirmed my suspicion that the word here is not the German one with mm and a sexual connotation, but actually a yiddish variant with a different meaning:

"A few years ago a couple of women in my office asked me if I knew what the word verklempt meant. I didn’t. They asked because some character on a television show called Saturday Night Live used it all the time. People always think I know the weirdest things. I looked up the word in a German dictionary and they said it was a Yiddish word meaning closed in, as though the pressure of the world was proving too much with which to cope. "
