Nuts and Bolts: lalochezia.

Lalochezia is a very new word that describes the pain-relief offered by swearing.

Most people will have personal experience of this, but it's always nice to have a posh Greek name to dignify us in our agony.

(No, it's been proved scientifically proved. Richard Stevens at Keele University is your man. Thanks, Mr Stevens.)

Thing We Realised Long Before The Scientists: lalochezia. This word, I should imagine, comes from the Greek lalos, speech or chatter, and -chezia comes from...um, well, dyschezia is another word for constipation, so you can work this one out for yourself.
