She’s displeased and thinks you should know better.
Having the hands on the hips or “arms akimbo” is to display like a peacock, even in people! It makes the body take up more space and hence appear larger so as to assert dominance. All the fingers also curl inward so that they point toward the crotch drawing attention in that direction which punctuates the point even further. The thumbs might also be tucked into the belt or into belt loops serving to “frame the genitals” as in the “cowboy pose.” The message said is “There are issues here”, “Things are not right”, “I’m standing my ground” or “I’m a virile male so check me out!” Women can also be seen holding the posture although more rarely, and when they do, they will hold their hands on their hips and point their fingers to their buttocks. Pointing therefore, puts emphasis on our best assets while we state our case. Fingers pointed backwards as women do more often, is a more inquisitive posture than an authoritarian one.
The hands on hips gesture is one of the ways men puff out to appear more dominant and attractive to the opposite sex and repel competition from the same sex. The cue cluster accompanying the hands-on-hips also includes an upright posture, chin up, chest out and the legs at slightly wider than shoulder width. The hands-on-hips is also a “ready posture” when it does not accompany more dominant cues in the cluster. In this case, it appears like a runner at the gate prepared to jump at an opportunity whatever it might be.
