The Spanish term for a boy’s traditional fifteenth-birthday celebration counterpart to a quinceañera is quinceañero.
Quinceañero is the masculine counterpart of quinceañera, whose original meaning refers to a girl turning fifteen. The word can describe the boy celebrating the birthday and, in some usage, the celebration itself. The feminine and masculine forms follow Spanish grammatical conventions.
Quinceañero celebrations are less widespread and less standardized than quinceañeras. Families may adapt familiar elements such as formal clothing, a religious service, a reception, speeches, dancing, or a symbolic presentation. There is no single worldwide format.
A chambelán is different: that word usually identifies a male attendant or escort in a quinceañera court. Cumpleañero is a general Spanish word for a birthday celebrant, not the specific traditional counterpart.
