Laughed and shook her hips? Good for wife! (7)


I believe the answer is:


'laughed' is the definition.
(giggling is a kind of laughing)

I don't understand the remainder of the clue.

(Other definitions for giggled that I've seen before include "Tittered" , "Laughed in silly or nervous way" .)

I've seen this clue in The Times.
