Whats a swear-jar?

A jar you put money into each time you swear.

Take off the lid and swear into it.

Something that weak people feel they need because they cannot control the words that come out of their mouth. How sad to need one.

A while back I needed money for something special and didn't have enough. So I started swearing up a storm until my swear jar had enough money in it to buy what I wanted!

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.

I have no idea what it is

A swear jar 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.

A jar that you put money into every time you swear. A way to save money toward some goal.

A jar you put money in if you curse.

it's a jar in your house that everytime someone says a swear word, you have to put a dollar in.

Then you use the money for a vacation or a pizza dinner or something.
