You bend your arm at the elbow, raising the forearm and hand upward, then lower them in front of you to the initial position.
What does it mean?
1."Nothing can be done, one can only accept the situation": It most often expresses not aggression or frustration, but rather acceptance of the situation as something inevitable.
2. Self-irony: In this context, it is used to reduce tension.
3. Tiredness from unsuccessful attempts to change something.
4. A mild form of polite refusal: It allows one to avoid a direct "no" and unnecessary explanations.
This gesture is perceived as informal and is mainly appropriate in casual conversation between acquaintances. In business settings, it is usually replaced with words. The overall meaning of the gesture largely depends on intonation and facial expression. The gesture itself is not considered rude, but it may be read as a sign of passivity or an indifferent attitude toward circumstances.
