adj. (American).—Stupid. [The term though only dialectical in England is pretty general in U.S.A. It is given by Murray as a variant of CHOLTER-HEADED, which in turn is another form for jolt or JOLTER-HEADED. Chowder is properly a kind of hotch-potch, and applied to the intellectuals would imply ‘confusedness,’ and hence idiocy.]
