My question does not regard the word, but a facial expression.
Albert Einstein’s picture of sticking out his tongue is so popular and humorous, but I’ve been wondering under what situation the picture was taken, and what the picture connotes, every time I’ve seen it.
In our country, the gesture of sticking out one’s tongue means rejection (No!), denial (I told you a lie) or embarrassment (I made a mistake). This gesture is more often made by children rather than by grown-ups.
What does the gesture of sticking out one’s tongue mean as a body language among Anglo-Americans?
