Sometimes, when I remember, and when I am trying to be polite (despite being mightily peeved at something or other), I will exclaim "Bolshoi!" instead of shouting the name of the food that comes out of bulls, after the bulls are all done with it.
It's a few semi-tasteful steps removed from the more obvious "Oh, bullcrap!" Plus, I'd like to think that this small effort on my part helps the people around me keep some calming distance between that particular nitrogen-fixer and their own finer sensibilities.
Which is to say, my silly, sly substitution hopes to introduce some room to maneuver and to squeeze in an ability to have sidesteps kept handy for the squeamish. For some people, keeping bull manure far apart from sensitive olfactory equipment, is a must. It's an aural-oral sort of thing.
No matter how organic people say they are, for example, I've discovered very few of them really want to contemplate bull manure while they are just starting to tuck into their beefsteak entrees.
