You Say A racial incident, natch. Assistant principal has all five touch the top of a bottle of liquid dish detergent with their fingers, then touch their tongues.
Group shrieks bloody murder, wants assistant principal dismissed or hanged, whichever comes first.
School district cringes. Probably it won't. There's the racial angle for one thing. TV and movies seem by now to have liberated most Americans from delusions that they can't say pretty much what they want to, where they want to, when they want to, because that's what Americans on the screen do more and more of. I've grown accustomed, wherever and whenever, to overhearing all the unseemly expressions I learned in the First Christian Church Boy Scout troop, circa 1954.
