How do the boys describe greasers?

From the text:

We're poorer than the Socs and the middle class. I reckon we're wilder, too. Not like the Socs, who jump greasers and wreck houses and throw beer blasts for kicks, and get editorials in the paper for being a public disgrace one day and an asset to society the next. Greasers are almost like hoods; we steal things and drive old souped-up cars and hold up gas stations and have a gang fight once in a while.
