But then if, in the heat of anger, you invite someone to “take an aeronautical intercourse on a horizontally mobile toroid-shaped pastry,” you aren't really talking about an equine activity.

It always amuses me that people won't say fuck or fucked in common speech but they will say someone was screwed, shafted or hosed, each of which carries all the same meanings.

Now you often hear otherwise polite and PC folks, even children, saying that someone or something sucks. Evidently they are completely unaware of the complete expression from which this is drawn and never think about what it might be that is being sucked.
