Don’t forget your hood when you leave the house. To you I suppose I would be a ginny/mick mackerel snapper. Oh BTW, that’s the proper way to spell the insult.
Not if you are referring to being half Italian! That would be Guinea or ginney. Ginny is a reference to popular Italian garb Ginny T’s, now more commonly known as wife beater shirts.
Dago or Wop would have been more appropriate to your Irish half Catholic upbringing.
