There is no denying that Dominicans have their own version of Spanish. We have so much slang (like vaina and vacano) that have become a part of the everyday language. While they aren't officially in the dictionary, they might as well be, because you won't find a Dominican who doesn't widely use most of the slang terms ahead. If you're Dominican, you'll nod so hard. If you're not, you'll laugh at the meanings and might want to pick up a word or two.
