Bring some water with ya!
This is a phrase that, standing alone, seems very innocent, but when a white, older male shouts it at an immigrant who has just said that they are heading back to their homeland soon, it becomes incredibly non-P.C. If you're still confused, check out the example:
Immigrant in America: I won't be around for the next month. I'm traveling back to my homeland in Africa.
Dumb American: Oh yeah? Bring some water with ya!
Immigrant in America: (Confused look on face...thinks to self, "should I be offended?" and walks away)
(This would also work for Mexican immigrants.)
