Nicknames could represent ethnicity, social standing, or social reputation, all of which are thought to have social significance. Nicknames have a form of intimacy and familiarity with one another, and they also may have negative consequences such as shaming, bullying, humiliation, etc. This study looks into the Javanese people's nicknames and their meanings, the sources of nicknames, the response when others address them, and the social functions of using nicknames. A survey of thirty respondents from East Java who have and are addressed by their nicknames instead of their real names has conducted using a questionnaire to find out the answer. The results showed the meanings of nicknames are highly diverse from one another. It turns out that the sources of nicknames are coming from their physique or appearance, their nature or characteristic, daily habits or job, real name pun, family members, certain events, and unknown sources. Also, most nicknames represent intimacy rather than shaming. Responders could accept their nicknames with various responses such as pleased, normal, and disturbed. Therefore, nicknaming people in East Java can develop a new identity with multiple meanings and origins by stressing intimacy above shaming.
