One cannot freely analyse a person's body language based on simple observation. While there are universal emotions for all humans, there are no universal body gestures and signs!
A person's culture and origin should always be taken in consideration.
The examples you've given are stigmatized definitions which may lead to completely inaccurate deductions if not used correctly.
Always establish a person's baseline of behaviour. Everyone has different one. Gestures are not universal for all humans.
Anyway, thank you for this read. Cheers :)
