yes wofa, a pica is any 'abnormal' eating habit, and the most common one is dirt, but why a pica?

its from the latin name for a blackbird/magpie-- who eat (or at least pick up in their mouth and carry away) many sorts of things.. so a pica is to eat like a blackbird/magpie, and to eat non-food items!

i didn't bother to look up pica as type font.. perhaps someone else will.

sometimes its seems we have discussed every word there is.. but then, sometimes we are just jaded.. most of us here knew the term pica (as an abnormal eating habit) and we let it slide by..we have to open our eyes, and find new and interesting words..
