"Lelei mea uma, Tausoga (literal)". Cousin in Samoan is Tausoga. Instead of the word "Tausoga/Cousin", Samoans would use the word "Uso" (brother or sister, depending on who's talking), as they get tongue-tied around the word tausoga in this context, and uso denotes the closeness of the relationship.
