Cuz is a colloquial way of saying “cousin”. It could also take on the same meaning of bro where bro literally is a shorter way of saying brother but takes on the meaning of “friend”. There is a great spanish equivalent in Tío which literally means uncle but in Spain means “friend”

"cuz" = "cousin"

Gracias Nincy. o (Nancy)??

“Cuz” es una palabra más corta para la palabra “cousin”(primo). Es como diciendo en español “Cómo andas primo”.
