What is the definition of corpsing in drama?

Corpsing in drama refers to an actor breaking character and inadvertently laughing or smiling during a performance. It can be caused by various reasons, such as finding the scene particularly humorous, being tickled by a fellow actor, or simply losing control of one's emotions. Corpsing can be disruptive to the performance and may lead to embarrassment for the actor and potentially ruin the scene. To avoid corpsing, actors employ techniques such as staying focused, maintaining concentration, and practicing emotional control during performances.
