Explanation
In Thailand, the thumbs-up gesture is widely understood as a sign of approval, agreement, or 'good job,' similar to its use in many Western cultures. It is considered polite and friendly in everyday contexts, such as expressing thanks or acknowledging a job well done. However, it is not used for counting (e.g., 'one') as in some cultures, and it should be avoided in very formal or hierarchical settings where a wai is more appropriate.
Local Tip
Use the thumbs-up casually with friends or in informal settings, but always pair it with a smile to ensure warmth and avoid any perception of sarcasm.
How it compares elsewhere
The thumbs-up is considered an obscene insult, equivalent to showing the middle finger.
The gesture is highly offensive and vulgar, especially in the northern regions.
Commonly used as a positive sign, but can be interpreted as sarcastic or dismissive in some contexts.
