Euphemisms are generally used to change something icky into something more palatable. As George Carlin said, “Sometime in my life—no one asked me about this—toilet paper became bathroom tissue. The dump became the landfill. And partly cloudy became partly sunny.”
I was in a medical center the other day, where an information station was set up under an umbrella. Emblazoned on the umbrella were the words SERVICE AMBASSADOR. I find nothing distasteful about the word INFORMATION, but I am entertained by the thought of a group meeting to find a supposedly better (and definitely more pompous) description of the services offered under that umbrella. SERVICE AMBASSADOR: Do you suppose the, ahem, ambassadors who staff that desk need congressional confirmation?
