Jureur

A "jureur" (masculine) or "jureuse" (feminine) is a French term, often used informally or colloquially, referring to someone who swears or curses frequently. It describes a person who uses profanity habitually in their speech. The term implies a propensity for using vulgar language, particularly oaths and expletives. It is not a clinical or formal designation, but rather a descriptive label based on observed behavior. The intensity of the label can vary depending on the context and frequency with which the individual uses profanity.
