1. Cruising: Greasers are known for their love of cars, and often spend their free time cruising around town in their hotrods. This is a way for them to show off their cars and meet other greasers.
2. Fighting: Greasers are often portrayed as rebellious and tough, and fighting is seen as a way to prove their strength and status. This could be against rival gangs, or even just to settle petty disputes.
It's important to note that these are just stereotypes, and not all greasers engage in these activities.
