Answer:
The socs are smart, upperclass, and smart kids who come from wealthy families. And greasers are trouble-making and stupid punks. (That's how they're portrayed) So the socs kind of look down on the greasers and the fact that the greasers think they're so tough and cool makes the socs even angrier. Sometimes opposites DONT attract.
== because the socs were losers and jerks and beat up greaser for fun so the awsome greaser wooped them in the rumble they were like POW, HIT SMACK PUNCH! and they won. ==
The Socs fought the greasers because they thought they were just better, due to being richer.
