Quote from Ebo:
Popularized by GregS's fellow countryman, Mike Meyers on SNL, it is presumed to be Yiddish. But also may come from an older German word. There is a current German verb "klemmen" which means "to wedge." It can also be used in other combinations/compounds to mean "tension." Thus Verkempt (ferklempt, fahrklemt and etc) could mean a "tightness of the heart" as in emotional.

Quote from Bluedog:
correct...
This is what a verklempt lools like!![]()
