The usual male Spanish term for a boy celebrating a traditional fifteenth birthday is quinceañero.
Quinceañero is the masculine counterpart to quinceañera. The distinction matters because quinceañera traditions historically centered on girls, while some families and communities have adapted the milestone for boys. A quinceañero celebration may retain familiar elements such as formal clothing, a court, a ceremony, and a reception, but the details are not fixed.
The word chambelán describes a different role. A chambelán is commonly a male member of the honoree’s court or an escort, not the central birthday celebrant. Likewise, padrino means godfather or male sponsor and does not name the honoree.
Contemporary celebrations show considerable flexibility. Families may use different names, combine traditions, or create a fully personalized event. The masculine term is therefore useful for identifying the celebrant, while local practice determines which rituals accompany the birthday.
