How big is a rattle snake?

A nickname is a short, clever, cute, derogatory, or otherwise substitute name for a person or thing's real name (for example, Bob, Rob, Robby, Robbie, Robi, Bobby, Rab, Bert, Bertie, Butch, Bobbers, Bobert, Beto, Bobadito, and Robban (in Sweden), are all short for Robert). As a concept, it is distinct from both pseudonym and stage name, and also from title (for example, City of Fountains), although there may be overlap in these concepts.
