belly laugh

The phrase "belly laugh" refers to a deep, hearty, and uncontrollable laughter that emanates from the core of a person's body. It is often accompanied by a convulsive movement of the diaphragm, causing the stomach to shake or "jiggle." Belly laughs are typically associated with genuine amusement, extreme hilarity, or finding something extremely funny. They are often considered to be the most sincere and satisfying type of laughter.
