Ha \Ha\ (h[aum]), interj. [AS.]
   An exclamation denoting surprise, joy, or grief. Both as
   uttered and as written, it expresses a great variety of
   emotions, determined by the tone or the context. When
   repeated, ha, ha, it is an expression of laughter,
   satisfaction, or triumph, sometimes of derisive laughter; or
   sometimes it is equivalent to "Well, it is so."
   
[1913 Webster]


         Ha-has, and inarticulate hootings of satirical rebuke.
