That's true; but suppose the Yankees 'ave shot the men and cabbaged the boat?
All except one—that one lay in the plate of the man from whom I had cabbaged the lot.
Who's the nervy party with the chin whiskers that's cabbaged Hinpoha?
mid-15c., caboge, from Middle French caboche "head" (in dialect, "cabbage"), from Old French caboce "head," a diminutive from Latin caput "head" (see capitulum). Introduced to Canada 1541 by Jacques Cartier on his third voyage. First written record of it in U.S. is 1660s.
The decline of "ch" to "j" in the unaccented final syllable parallels the common pronunciation of spinach, sandwich, Greenwich, etc. The comparison of a head of cabbage to the head of a person (usually disparaging to the latter) is at least as old as Old French cabus "(head of) cabbage; nitwit, blockhead," from Italian cappuccio, diminutive of capo.
