Euphemism usage is now an art form. Toilet has its origins as the term "toilette" as m'lady's little chore of making up her face.
True, true. I don't think there's anything recent about it -- look at the Victorians! They had euphemisms for every slightest indelicacy in life. Seems to me we were foolish to strip away those illusions. Better to keep our gaze high than to wallow in the mud.
