The traditional Spanish term for a boy celebrating a male quinceañera is quinceañero.
Quinceañera is the feminine form associated with the traditional fifteenth-birthday celebration for a girl, while quinceañero is the masculine form. In practice, terminology varies by country, family, and community, and some people use broader expressions such as fiesta de quince años for the event itself.
Historically, the celebration has been strongly associated with girls and young women. Male versions exist, but they are less standardized and may use the same music, formal clothing, family rituals, and banquet structure as a traditional quinceañera.
The word should not be confused with padrino, which means a sponsor or godparent, or with chambelán, a male court attendant. Those terms describe roles connected with the event rather than the young person whose birthday is being celebrated.
