Distracting backgrounds behind the subject are the bane of camerawork. Aside from selecting another background, the best way to cope with this situation is to employ a wide lens aperture, resulting in a shallow depth-of-focus. The subject will remain sharp while the background will be blurred.

But along with a blurry background something curious is likely to happen, especially if there are bright specular highlights. The blurred highlights will turn into circles, big or small, depending on the size of the lens opening. This is officially called "bokeh", pronounced as in a "bouquet" of flowers.
