The Socs are superficial, privileged individuals who enjoy their material possessions and like to have parties. They also enjoy fighting the Greasers and picking on kids who are not wealthy. Cherry mentions to Pony that the Socs are pretentious and fake. Socs are more concerned with their appearance and status than they are with developing authentic relationships. Similar to the Greasers, their "code" would be to stick up for one another. For example, the Socs are quick to retaliate after Bob Sheldon is murdered and seek to avenge his death.
The Greaser gang consists of troubled youths who have difficult home lives. They enjoy hanging out, committing petty crimes, and fighting Socs. They are extremely loyal to one another and selflessly help each other when they are in difficult situations. Darry gives them a place to stay if any of them get kicked out of their homes, and each member is willing to fight in order to protect another Greaser. Unlike the Socs, the Greasers have authentic relationships and value each other on an individual level.
