Ever shot a stream of saliva out from under your tongue like a human sprinkler? If so, you’ve “gleeked.” This quirky (and often embarrassing) phenomenon has gained viral fame on TikTok, but for many, it’s an unintentional surprise.
What is Gleeking?
Gleeking is the sudden ejection of saliva from the sublingual or submandibular glands located beneath your tongue. It can happen accidentally—usually while yawning, talking, or eating—or on purpose, if you’ve mastered the technique.
Why Does It Happen?
When you unconsciously press on the glands under your tongue—like during a wide yawn or when your tongue is in just the right spot—it can trigger a quick spray of saliva. It’s harmless but attention-grabbing.
How to Gleek on Purpose
TikTokers have turned gleeking into a party trick. While there’s no universal method, here are common techniques:
- Build up saliva by yawning or eating sour candy.
- Push your tongue hard against the roof of your mouth while sticking your lower jaw out.
- Suck air beneath your tongue, then quickly press your tongue upward.
Can Everyone Do It?
There’s no research on how many people can gleek voluntarily, but it seems to depend on individual anatomy and tongue control.
Want to stop spraying your dinner date?
- Avoid pressing the floor of your mouth when eating or yawning.
- Stay hydrated and swallow regularly.
- Brush and floss daily to reduce irritation.
- Avoid overly sour foods that spike saliva production.
If gleeking becomes frequent or concerning, talk to your dentist or doctor—it could point to a salivary gland imbalance or other minor health issue.
