It seems like you're asking about the sociologist Walter B. Miller's theory on lower class culture. Miller proposed that certain groups in society, particularly those in the lower social classes, develop a unique set of values and norms that are different from the mainstream culture, which he referred to as "focal concerns". These focal concerns include trouble, toughness, smartness, excitement, fate, and autonomy. According to Miller, these focal concerns lead to delinquent behavior when they come into conflict with the values and norms of the mainstream culture. Therefore, the answer to your question is "Focal concerns".
