The common Spanish term for a male who celebrates a traditional fifteenth birthday is quinceañero. It is the masculine counterpart to quinceañera, the term most widely associated with the celebration and, in many contexts, its female honoree.
The masculine form is less familiar internationally because quinceañera traditions have historically focused more often on girls. However, boys and young men may also have fifteenth-birthday celebrations, sometimes using quinceañero or a local equivalent.
Quinceañero should not be confused with chambelán. A chambelán is a male member of the ceremonial court, while the quinceañero is the person whose fifteenth birthday is being celebrated. Likewise, a padrino is generally a sponsor or benefactor, not the honoree.
Language and practice vary by community. Some families use Spanish terms, while others describe the event in English as a fifteenth-birthday celebration.
