When a person tries to control everything around them because they need to be the center of attention. No one likes them because they play people and just dig themselves into a hole. They also lure people in with false promises and lies then throw them away like garbage. Most people who are not chill are usually ousted from societies and end up running away to other parts of the country because they realize no one likes them.
