What is gleeking meaning?

Gleeking is a term used to describe the act of involuntarily spitting saliva from the mouth when yawning, laughing, or chewing. It occurs when the submandibular gland, located beneath the tongue, releases saliva at a high velocity due to pressure from the tongue. Gleeking can be a natural occurrence for some people, but it can also be intentionally learned and performed as a party trick. Gleeking is not harmful and does not require any medical attention.
