A male celebrant of a quinceañera-style fifteenth birthday is commonly called a quinceañero.
The term is the masculine counterpart of quinceañera and is used for boys or young men whose fifteenth birthday is marked with a similar celebration. The event itself may still be described as a quinceañera in some communities, while other families use quinceañero or a more general phrase for the birthday party.
Spanish gendered nouns commonly change their endings, with -a often marking feminine forms and -o marking masculine forms. The distinction describes the celebrant; it does not require one universal ceremony format.
Celebrations for male honorees are less standardized in popular descriptions than traditional quinceañeras for girls. Families may adapt the clothing, court, music, religious service, and symbolic rituals to fit the celebrant and local custom.
