Fabrizio del Wrongo writes:
The dance is sometimes said to reenact a violent “discussion” between a pimp and a prostitute. It includes mock slaps and punches, the man picking up and throwing the woman to the ground, or lifting and carrying her while she struggles or feigns unconsciousness. Thus, the dance shares many features with the theatrical discipline of stage combat. In some examples, the woman may fight back.
The modern versions I’ve seen include less throwing and more fighting back.
