What does the word "lalochezia" mean?

Lalochezia is the use of vulgar or foul language to relieve stress or pain. Or the emotional relief gained by using abusive or profane language.

It derives from lalos, a Greek word meaning “speech” or “chatter,” which is the origin of the fairly familiar English suffix –lalia, root of a crop of medical and morphological terms concerned with speech or language.

The final “–chezia” of lalochezia, comes from a Greek root, khezo, literally meaning “I defecate.”

So the term literally means “defecating out of your mouth.”
