Inside the Viral 'Gleeking' Craze: Video Proof, Biology, and Dublin Fringe Reactions
By Elena Rostova
Despite thousands of instructional tutorials circulating online, not every mouth possesses the necessary geometry. Achieving a controlled saliva ejection reflex requires specific anatomical conditions. The length and flexibility of the lingual frenulum play a dominant role. Individuals with ankyloglossia, commonly known as tongue-tie, rarely manage it because their tongue cannot achieve the backward upward sweep needed to compress the duct.
Those who can execute the trick typically follow a recognizable pattern. First, they stimulate saliva production, often by thinking about sour citrus or pressing the tongue lightly against the teeth. Second, they swallow to clear excess fluid from the oral cavity so the mouth floor remains dry. Finally, they swiftly press the tip of the tongue against the hard palate while snapping the lower jaw slightly forward. The action exerts localized hydrostatic pressure, forcing the clear serous fluid out before it spreads across the gums.
