A quinceañera’s male dance attendant is commonly called a chambelán.
A chambelán is usually part of the celebrant’s court and may participate in a choreographed entrance or formal dance. Depending on local custom, he can be a relative, friend, or other trusted participant. Some celebrations have one principal escort, while others include several male attendants.
The word is regional and not every Spanish-speaking community uses the same terminology. A quinceañera’s attendants may also be described with terms such as escorts or members of the court, especially in English-language settings.
Chambelán should not be confused with padrino, which generally means godfather or sponsor. A padrino may help support the celebration, but that role is different from being a dance attendant.
