hysterical

This term oscillates between two extreme emotional poles: intense panic and intense amusement. When describing fear, it suggests a total loss of self-control and a breakdown of rational thought, often associated with high-stress or emergency situations. In a social or comedic context, it describes laughter that is so overwhelming it becomes physical and uncontrollable. While the psychological sense refers to a specific clinical history of emotional excess, in modern casual speech, it is most frequently used as a hyperbolic synonym for extremely funny.
