Kvetching
Squeezing a grievance out of any situation
Derived from the Yiddish 'kvetshn', meaning to squeeze, kvetching describes the ability to squeeze a grievance out of any situation, however favourable. The impulse to kvetch predates Yiddish by several thousand years. In the Book of Numbers 11:4-6, the Israelites, freshly liberated from slavery in Egypt, turn to Moses with a complaint: they miss the food.
We remember the fish we ate in Egypt at no cost. Also the cucumbers, melons, leeks, onions and garlic. But now we have lost our appetite; we never see anything but this manna!
