The Collaborative International Dictionary of English v.0.48:

Turkey-trot \Tur"key-trot`\, n.
   An eccentric ragtime dance, danced with the feet well apart
   and with a characteristic rise on the ball of the foot,
   followed by a drop upon the heel. The original form, owing to
   the positions assumed by the dancers, is offensively
   suggestive. Similar dances are the

   bunny hug and

   grizzly bear, so called in allusion to the movements and
      the positions assumed by the partners in dancing.
      [Webster 1913 Suppl.]
