1 Chiefly Midland and Southern U.S. askew; awry.
2 Positioned diagonally; cater-cornered.
Etymology: Catawampus is of uncertain origin, though its first element, cata- likely derives from the adverb cater meaning "diagonally." The second element may be related to the Scottish term wampish meaning "to wave about or flop to and fro." It entered English in the mid-1800s.
