What is the definition of frottage?

Frottage is defined as a form of sexual expression that involves the act of rubbing against the body of another person for sexual pleasure. This behavior can occur in various contexts, often in crowded public settings where physical contact is more likely to happen without the consent of the other person involved. The essential component of frottage is the physical act of rubbing rather than any force or explicit sexual intention underlying the interaction. This distinguishes it clearly from other concepts related to sexual attraction or interpersonal relationships, as it is specifically focused on the act of physical contact for sexual gratification.
