Used in South Texas to describe a Mexican-American. Usually taken (by Mexican-Americans) to be pejorative and offensive, similar to the *N* word (but not as strong). Also, in the same way that blacks often call each other the "N" word in jest, I've heard young Mexican-American males call each other "meskin" (e.g. "what's up, meskin?) in jest.
