Passive-aggressive behavior is characterized by a pattern of passive hostility and an avoidance of direct communication. Inaction where some action is socially customary is a typical passive-aggressive strategy (showing up late for functions, staying silent when a response is expected). Such behavior is sometimes protested by associates, evoking exasperation or confusion. People who are recipients of passive-aggressive behavior may experience anxiety due to the discordance between what they perceive and what the perpetrator is saying. Application. Psychology.
