A "gang" is a group of individuals who come together for a common purpose, often sharing similar interests or activities. Gangs can be formed for various reasons, including social, economic, or cultural factors. While some gangs focus on positive community engagement, others may engage in illegal activities, such as drug trafficking or violence. Gangs often have their own symbols, names, and codes of conduct, which help to establish identity and loyalty among members. They can be found in many places around the world, and their influence can vary significantly based on local circumstances and societal conditions.
