The masculine Spanish term for a boy celebrated in a fifteenth-birthday coming-of-age tradition is quinceañero.
Quinceañero is formed from the same quince-based idea as quinceañera, but uses a masculine ending. Although quinceañera celebrations have historically centered more often on girls, boys can also mark their fifteenth birthdays with a comparable event. Families may call the celebration a quinceañero or use other regional expressions.
The format is not standardized. A boy’s celebration may include formal clothing, a reception, speeches, dancing, relatives, and religious elements, depending on local custom and family preference. Some families use a fully traditional format, while others create a modern party with only a few symbolic details.
Quinceañero should not be confused with padrino, which means a sponsor or godparent, or with chambelán, a male member of a formal court in some celebrations. Those words describe roles, not the fifteenth-birthday celebrant.
