well... the word bokeh is really just a synonym for blur isn't it?!

I guess there's some differentiation in photo-lingualism where the same "amount" of blur can still create a different "quality" of bokeh because of differing lens qualities such as diaphragm shape and aberration.

But technically any out-of-focus-blur is bokeh, whether it looks good or not, then it's just either ugly bokeh or nice looking bokeh... but that's really just a matter of taste anyway.
