What is "negerhollands"

Negerhollands ( English translation: Negro-Dutch) was a Dutch-based creole language that was once spoken in the Danish West Indies, now known as the U.S. Virgin Islands. Dutch is its superstrate language with Danish, English, French, Spanish, and African elements incorporated. Notwithstanding its name, Negerhollands draws primarily from the Zeelandic rather than the Hollandic dialect.
