A person's nickname:
A sobriquet is a person's nickname, most often given to an individual by another but, sometimes, it is assumed by the person. Sobriquets are usually familiar names used in place of a person's given name. These nicknames don't usually require an explanation. Oftentimes the sobriquet becomes more widely known and familiar than the individual's real name.

The sobriquet can apply to a specific person, a group of people or a place, such as a city or town. Source: Definitions.net
