While the quality is often found in photos of flowers, Bokeh is pronounced more like "Boca" (as in Raton) than "bouquet". And while it usually appears in out-of-focus backgrounds, it goes beyond simply shallow depth-of-field. And, yes, it is blurry, but a special type of blurry.
Bokeh, from the Japanese term "Boke" (everyone pronounced it wrong, so someone changed the spelling in English), describes the aesthetic qualities of out-of-focus points of light, or highlights, which are introduced by the optics of a lens. In a way, bokeh is a beautiful result of imperfection.
Some folks feel the best bokeh has an undefined, Gaussian blurred edge. Others like more defined shapes which often reveal the shape of the lens aperture. How about you?
