An undergraduate social club, often referred to as a 'frat, ' is an organization of college students who come together to form a community. These clubs typically provide members with social activities, academic support, and leadership opportunities. Fraternities and sororities are the most common type of undergraduate social club, but there are also other types of organizations such as honor societies, service clubs, and professional organizations. Fraternities and sororities often have a strong focus on philanthropy and community service, while other clubs may focus on specific interests or hobbies.
