"a usually familiar or humorous but sometimes pointed or cruel name given to a person or place, as a supposedly appropriate replacement for or addition to the proper name.", or a name similar in origin and pronunciation from the original name.

It is not interchangeable with a term called "short-for". It can also be the familiar or truncated form of the proper name, which may sometimes be used simply for convenience (e.g. "Bobby", "Bob", "Rob", or "Bert" for the name Robert).

The term hypocoristic is used to refer to a nickname of affection between those in love or with a close emotional bond, compared with a term of endearment. The term diminutive name refers to nicknames that convey smallness, hence something regarded with affection or familiarity (e.g., referring to children), or contempt.

The distinction between the two is often blurred. It is a form of endearment and amusement. As a concept, it is distinct from both pseudonym and stage name, and also from a title (for example, City of Fountains), although there may be overlap in these concepts.

During an interview with New Zealand radio station 'ZM', Galecki jokingly recalled his childhood relationship with his mother. As a child, he was well known for making up long, epic stories and tales. In such situations his mother used to make him play the "quiet game" where he had to see how long he could go without talking. He also recalled that despite being a loving mother, she was also very tough. One phrase she would lovingly use was, "I love you, now get out."
