Are there gestures considered offensive in Thailand?

The “OK” sign
A circled thumb and index finger, often a sign for “okay” or “I understand” in many cultures, can actually convey a sexual connotation in Thailand. While the gesture has more or less evolved to its more international meaning among Thai adults, children will still use it to tease one another or get away with non-verbally communicating something rude behind their parents or teachers’ back.

Come here
Termed the “kwang myy,” the Thai gesture for “come here” is actually similar to what Westerners would use for “go away,” with an open palm angled down, moving upward and downward repeatedly.

Thumbs up
Traditionally, giving someone the “thumbs up” gesture is similar to giving them the middle finger – ultimately derogatory in nature. While adults in Thailand today have adopted its more international meaning of approval or a job well done, it’s still common for kids to exchange the gesture during a childish argument.

Don’t point your feet: Pointing your feet at someone, raising your feet higher than someone’s head, or simply putting your feet on a desk or chair are considered extremely rude in Thailand.

Don’t touch someone’s head: While the feet are considered the lowest and dirtiest parts of the body, the head is revered as the most sacred. Never touch someone’s head or hair — this includes playfully ruffling a child’s hair.

Don’t point: Pointing at someone is considered rude in many cultures but particularly so in Thailand. If you must indicate a person, do so by lifting your chin in their direction.

Don’t throw things: Tossing an object or money in someone’s direction is rude. Take time to hand things to people properly, face up, preferably with your right hand. Unfold money when paying someone.

Use your right hand: The left hand is considered dirty, as it is sometimes used for “toilet functions.” Always use your right hand to pass objects to someone and when paying.
