When I was in school, back in the Old Silurian times, they hadn’t come up with the term “Public Display of Affection,” probably because we wouldn’t dare do such things in class. I remember the siblings discussing it, so it apparently filtered in during the 1970s. Truth be told, I’m not sure if my own negative reaction to the concept is based on some sort of devotion to order or on sour grapes, inasmuch as I was never in a position to engage in such a thing myself.
Aw, heck, let’s put it as flatly as possible:
I’m not the prudiest prude who ever pruded, but seriously, it’s GROSS to be trying to teach and out of the corner of your eye see two people practically feeling each other up.
Especially two people who, if pressed, will argue that they’re actual adults despite their teenage-crush mutual fondle session.
And while I’ve seen “prude” turned into an adjective before, this is the first time I can remember seeing it verbed.
