hilarity

This term describes a state of boisterous, high-energy amusement. It differs from mere happiness or amusement by implying an audible, outward expression of joy, typically characterized by uncontrolled laughter. It is often used to describe the collective atmosphere of a group rather than a quiet, internal feeling of mirth.

As an uncountable noun, hilarity cannot be pluralized or counted with numbers. To refer to a specific instance of this emotion, one must use partitive constructions such as a moment of hilarity or a fit of hilarity.
