Gleeking is when you stimulate the submandibular glands underneath your tongue into gushing a concentrated jet of pure saliva. Sometimes it happens naturally when you yawn (especially while eating Starburst) but it takes practice and concentration to gleek on purpose. Some advanced gleekers can squirt up to 10 feet in distance.
My brother in law Brandon can gleek on que! On a good day he can gleek over 6 feet!
