an expression that suggests something like, "Don't sweat the small stuff." The meaning stems from a song sung by a trumpeter, singer, and manager of Kay Keyser's orchestra, whose real name was Merwyn Bogue. He was given the nickname Ish Kabibble after the Yiddiah song he sang, called "Isch Ka Bibble" ("I Should Worry")
"Ish kabibble! That's nothing to worry about."
