I am an American (norteamericana) married to an Argentino and I am commonly called gringa. At first I was offended, but it was carefully and repeatedly explained to me that this is just a descriptive word for a foreigner from Europe or North America and not intended as an insult. After all, the Argentinos call each other Gordo, Flaco, Viejo, Negro, etc. In the family, I am affectionately La Tia Gringa, but it is not just family. On our block in Balvanera, when I am not around the local merchants routinely ask my husband "Donde esta la gringa?"
