Haitian Vodoun Culture Language (known as Langay and Langaj; literally "language") is a specialized vocabulary used in Haiti for religion, song, and dance purposes. It appears to not be an actual language, but rather an assortment of words, songs, and incantations – some secret – from various languages once used in Haitian Vodoun ceremonies.
