You should explain that she is confusing the terms.
"Bokeh" (not 'Bohka' btw), refers to the quality of out of focus objects and highlights.
What I think she means, is "DOF", and that she prefer very narrow depth of field.
Although, if she is indeed a Canon-shooter, the two 50's cannot be shot wide-open really, as they (at least the f1.4) become both soft and rather strange at those apertures (halo-effects on in-focus objects and also on objects that are out of focus).
Nothing wrong with playing with narrow depth of field (or even tilt-shift lenses with narrow depth of field as well), this is a creative decision.
- Who decided that you have to shoot at f22 to be a "proper photographer"?
I use whatever aperture that suit the situation, but for people in an environment, narrow depth of field can be really nice, you can even use the shapes in the "Bokeh" to add to your composition, as well as eliminate distracting elements in the background more effectively.
I think you are all a bit patronizing here, why does she deserve to be laughed of, just because she got a creative preference and confuse the terms a bit?
