Great Regulars: Soft language was the substitution, say,

of "bathroom tissue" for "toilet paper"; it was calling the dump the landfill and saying you were experiencing a "negative cash-flow situation" when what you really meant was that you were broke.

Mr. [George] Carlin had dozens of examples, and he could cite them for minutes on end, alternately rueful and disbelieving. But what came through, even as he shook his head and used one or more of the seven forbidden words to say how stupid we were, was his love of language itself and how various and evocative it was. Even the expletives--or perhaps especially the expletives.
