Wriggle \Wrig"gle\, v. i. [imp. & p. p. Wriggled; p. pr. & vb.

   Dan. vrikke.]
   To move the body to and fro with short, writhing motions,
   like a worm; to squirm; to twist uneasily or quickly about.
   [1913 Webster]

         Both he and successors would often wriggle in their
         seats,
         as long as the cushion lasted.           --Swift.
