SB's perfect use of the word "chooch" in his comment earlier compels me to put the word into colloquial circulation. I haven't heard the word uttered since I accidentally dropped a jar of vinegar peppers on my Uncle Johnny's patio after he warned me the lid was on too tightly and I couldn't handle it. "You're a little chooch, Kathy." I was nine.
For those without verbally-abusive Italian relatives who can't remember your name, here is the definition:
Chooch (n.) -- Italian slang for hardhead, blockhead, or any of a number of similar insults pertaining to one's obstinance or limited use of common sense.
"There is no convincing that friggin' chooch."
