Used by Haitian to speak to other Haitians who understand or speak both languages or parts of Creole and Spanish in Chile, Cuba, Puerto Rico and certain part of the United States Washington Heights (NYC) and Little Miami (Florida) but mainly in the Batey La luisa of the Dominican Rep, a small rural community where mostly Haitians live,

It's actually speaking Creole and Español at the same time by alternating from one language to another every 2 or 4 words.
Any Haitians who live in in the Dominican Republic for more than 5 years - speak CreoSpañol to one another every time they meet, greet or speak over the phone, text messaging even when they chat or when making comments online.
How Dominican Haitians, greet each other in the street of Washington Heights in CreoSpañol.
