A more thorough explanation:

Jactitation is a term used in law to describe a false boasting or claim that causes harm to another person.

• If someone falsely claims to be married to another person, it can be considered jactitation.
• A person who falsely boasts about owning a property that they do not own can also be guilty of jactitation.

These examples illustrate how jactitation can cause harm to another person. In the first example, the false claim of marriage can cause emotional distress to the actual spouse or family members. In the second example, the false claim of property ownership can harm the actual owner's reputation and potentially cause financial loss.
