Tongue jutting or tongue through compressed lips is used to signal a cheeky attitude when done amongst friends, but has a more sinister connotation in competitive situations since it indicates that a person has gotten away with something. “Tongue-jutting” is an indication that people figure they have gotten away with something, or have been caught doing something they shouldn’t have. However, in this case, the tongue is usually pushed through the teeth and doesn’t touch the lips.
The tongue jut gesture will be seen at the conclusion of an event such as signing a contract or winning a hand at poker by bluffing. Most of the time tongue protrusion happens when people feel they haven’t been caught, but sometimes it’s actually because they’ve been caught. Tongue through the lips or teeth can happen any place at anytime but signals the same thing almost every time, and that is that a person is doing something that is pushing the envelope of acceptability or has gotten caught doing something that is unacceptable.
