A false boast designed to increase standing at the expense of another. This used to form the basis of an ancient legal petition called "jactitation of marriage" wherein a person could be ordered by the courts to cease claims of being married to a certain person when, in fact, they were not married. The tort of slander of title is a form of jactitation.
