A more thorough explanation:

A barrator (also spelled barretor) is someone who causes arguments and lawsuits between people. They like to start trouble and keep things unsettled. They may do this in court or outside of it. A barrator is similar to a champtertor.

One example of a barrator is a person who encourages their friends to sue someone for a small disagreement. They may also try to start arguments between coworkers or family members. Another example is a lawyer who takes on cases that they know are weak, just to make money from the legal fees.

These examples illustrate how a barrator can cause problems and make situations worse. They may not care about the consequences of their actions, as long as they get what they want. This can lead to a lot of stress and expense for the people involved.
