Leer
There is a look or stare that you give to people to let them know a certain meaning without saying any words.
That look is sometimes more essential than a leader's speech and it could take control of one's attitude and movements.
Though the look could be harsh at times, it shows a strict control over a situation.
The look is usually given to enemies but can also be given to any stupid people or idiots.
The look is a significant expression that shows what a person currently feels.
A leer makes one cower or be alert.
