A more thorough explanation: Collusive behavior refers to a situation where two or more parties engage in a secret agreement or cooperation to deceive, manipulate, or defraud others, typically for their mutual benefit. In a legal context, collusive behavior is often associated with antitrust laws and regulations that prohibit agreements between competitors to fix prices, limit competition, or allocate markets.
