This photo is an ad of a Mr. Clean product. The statement used for the ad is a form of sexism because it implies that "moms" real job is to clean. This labels women as the housekeeper most of the time.
Here Burger King is using a woman with an open mouth, ready to eat with a caption that would have people thinking otherwise. This is a sexual way of promoting the sandwich because of how the woman is looking and how the sandwich is about the enter her mouth. It's a big exaggeration of how "good" the sandwich will be.
