A Napolitan' in my old Brooklyn neighborhood told me that "sfacheen" (as it's pronounced) means "jerkoff," and is part of a curse, as in "sfacheen a tu e tu patrie."
Ntra la porta tua lu sangu � sparsu,
E nun me mporta si ce muoru accisu...
E s'iddu muoru e vaju mparadisu
Si nun ce truovo a ttia, mancu ce trasu.
