It will. It will. What I mean is that there is no sport in firing blank rounds into a targetless space, if that makes sense. Or in beating a dead horse. No sense in my wasting a perfectly good snark when there's bugger all reason. Better to let it tick over until that moment of inspiration and there's a prime, juicy target just begging for a roasting
And no amusement in targeting the defenseless. You don't see martial arts students picking a fight with a lamprey, or an encrustation of seaweed, or waste a cruise missile on somebody that just farted do you now? and whats the point in taking on a target with the defensive capacity of a sea-squirt? sure, sometime a reply is due on principle because...well because they have the audacity to breathe air that may contain atoms which may, at some point have occupied the atmosphere above my toilet. Some things that walk on two legs are still to be classified as vermin, and what does one do with vermin, if not leave them a tidbit of poison?
Metaphorically speaking. Usually, at any rate. More or less the same principle as when somebody coughs up phlegm and hawks it onto the pavement.
Sometimes there are more suitable places than the pavement, but it isn't worth seeking out a special resting place for a loogie unless some or other incarnate gonad happens to be within gobbing range and have an ugly face that they turn your way.
