I think maybe the 精神小伙 seems like bad luck and the other 葬爱家族 is like emo?
In the videos, 精神小伙 (energetic young man) and 葬爱家族 (Clan of love burier) are the descriptions of the two rap artists who are doing a rap battle
精神小伙: 原指收拾的十分利落，看起来充满活力、很有精神的小伙子。现在几乎特指看起来很社会的土味小伙子 -- originally refers to a very neat looking and energetic young man. Now almost specifically refers to an earthy guy who looks very social
葬爱家族: 网络词语，葬爱家族是《劲舞团》中传出来的“网络组织”，好多玩家以杀马特造型示人，造型夸张，喜欢斗舞，并组成一个群体接纳另一个她(他)。现在大多指发型夸张，打扮狰狞且特立独行的反潮流的洗剪吹人士 (Nowadays, mostly refer to those who have exaggerated hairstyles and maverick anti-trend dresses)
精神小伙 (Energetic young man) --> Earthy social young man
葬爱家族 (Clan of love burier) --> Anti-trend hair and fashion style maverick
