I don't think that's a very common word in Spanish. Both my wife and I are fairly well-read Mexicans and neither of us had ever heard or seen the word. The Royal Spanish Academy's dictionary does include it, but they add the annotation "p. us.", which means "little used". So I don't think many people in either Mexico or, judging by the dictionary, Spain will know the word, but Spanish does vary quite a bit from country to country, so it might be more or less common somewhere else.
