How I felt when I saw only one definition for angry.
Angry is an emotion that highly contrasts and disagrees with the emotion, happy.
Someone feeling angry will usually have a lack of joy, a lack of judgement, a sense of inbred hate, and overall frustration.
The "image" of someone being angry is usually accompanied by violence, a frown, the furrowing of the eyebrows, and sometimes growling.
Angry is a synonym for mad
Bruce Banner turns into The Hulk whenever he gets angry (mad).
