Swear jar

A swear jar (also known as a swear box, swearing jar, cuss jar, or cuss bank) is a device to help discourage people from swearing. Every time someone utters a swear word, others who witness it collect a "fine", by insisting that the offender put some money into the box. The container may be made of glass, porcelain, or metal, and may have a lid with a slot. From time to time, the accumulated money may be used for some agreed-upon purpose, or contributed to charity.
