Gringo = Green Grow??
Interesting article here by American journalist Michael Kepp about a common brazilian response to when a non-brazilian says he/she has been living in the country for quite some time.
I, myself, have heard the "Ah, então você já é brasileiro" many times from people who I believe are saying it to make me feel welcome and at home.
Interesting discussion in the comments section about the origin of the word gringo. Can anyone tell me, though, if "gringo" is actually a little bit derogatory
