I zapped yesterday evening (4th May) when on Sky One - When text message goes bad (or something close to that) was talking about toothing as a new form of text messaging. The explanation was clear and last for about 1.5 - 2 minutes (not bad!) and they mentionned the web site (beginners guide to...) without giving the URL.
Let's see if your local pub will get filled with toothers next week-end!
