So dumb.

I've been wondering what they all meant.

The name is a blend of "South" and "Houston" from "south of Houston Street." Its name is the model for other new neighborhood acronyms in New York City, such as NoHo, for North of Houston Street, TriBeCa (Triangle Below Canal Street), Nolita (North of Little Italy), and DUMBO (Down Under the Manhattan Bridge Overpass)
