spaghetti code
     
         A pejorative term for code with a complex and
        tangled {control structure}, especially one using many
        {GOTOs}, {exceptions}, or other "unstructured" branching
        constructs.  The synonym "kangaroo code" has been reported,
        doubtless because such code has so many jumps in it.
