If someone waves or flicks their hand under their chin, you are not imagining it. In American English, people usually call this the chin flick. It is one of the rude hand gestures in America, and it is the one English learners ask about most.
Here is what it means, how it is different from sign language, and five other gestures that can get you in trouble in the U.S.
What Does Waving Your Hand Under Your Chin Mean?
Waving or flicking your fingers under your chin is an insult. In the United States, it is read as a rude dismissal, close to “get lost” or “I have no respect for what you just said. It is in the same family as giving someone the middle finger, even if it looks less obvious.
You may also hear it called a chin flick insult. The motion is simple: the back of the fingers brush up and off the underside of the chin.
It is not a friendly “thinking” pose. Resting your chin in your hand while you listen is normal. Flicking or wiggling the hand out from under the chin is the rude version.
Is the Chin Flick Sign Language?
No. This is not American Sign Language. People search for “what does flicking your hand under your chin mean in sign language,” but the gesture you are seeing in everyday life is a cultural insult, not an ASL sign.
If you need a real ASL meaning, look it up in an ASL dictionary. Do not copy this motion in a conversation and assume it is polite signing.
Rude Hand Gestures in America to Avoid
Hand gestures that feel normal in your first culture can be rude in America. If you are working, traveling, or meeting clients in the U.S., these American norms around gestures can cause the most confusion.
The Middle Finger
This is the most widely recognized obscene gesture in the United States. Raising the middle finger at someone is a direct insult. Even if you see it in movies, do not use it at work, in traffic, or with people you do not know well.
The Pinky Wave
Holding up a pinky at someone can be read as a crude insult about that person’s body. In traffic, it can also look like you are starting a fight. If you want to wave, use your whole hand.
Pointing at Your Forehead or Temple
Tapping or pointing at your temple with an angry face tells the other person you think they are crazy. In a tense moment, Americans read it as a serious insult, not a joke.
The V Sign (Watch the Palm)
Palm-out, the V sign is a peace sign in the U.S. Knuckles-out, the same shape is a strong insult in the U.K., Ireland, and Australia. If you use it in mixed company, keep your palm facing forward so it cannot be mistaken.
Thumbs-Up and the OK Sign
These are usually positive in the United States. They are not always safe worldwide. In some countries the OK sign or a thumbs-up can be offensive. If you work with international colleagues, do not assume a “safe” American gesture is safe everywhere.
How to Stay Neutral in American Conversations
You do not need a big set of gestures to look confident in American English. A simple whole-hand wave, a nod, and open hands while you talk will serve you better than copying movie insults.
If you are not sure what a gesture means, do not use it. Ask, or look it up, the same way you would check a new English word before you say it in a meeting.
