Back in the early 80's I went to a overnight summer camp that this was the standard punishment for swearing. I remember they even Had a slide of a kid biting the bar as they called it in their sales presentation, times were certainly different. How it was done is you would Be taken to the office and made to take a bite of this deodorant soap, I think it was Safeguard and they would make you chew it for A minute or two. If you swore and others were around you may have a bit of an audience. I remember having it a few times each year, it really got stuck to your teeth and the nearest water pump was a bit of a distance away.
