COORDINATION TONGUE

COORDINATION TONGUE:  the act of unconsciously sticking out one's tongue while engaging in an activity which requires mental skill, physical coordination, and/or dexterity.

I have noticed that all women of my acquaintance have their tongues sticking out while applying mascara.

"Coordination tongue" is quite noticeable with children while they are concentrating on different tasks, especially involving writing and sports activities.

Probably the most famous person using the technique is Michael Jordan as was evident especially while he was shooting free throws.
