portenpete said "It's used as a synonym for "fat"." (my italics) That's our point. It means sloppy, unkempt - but people equate it with being fat. One can be fat and still neat and kempt.
I do think all the definition you give is still about appearance, not behavior, and don't see how they apply to Tripp, but this is definitely one of those threads that goes nowhere. Over and out.
