Quinceañera:
The quinceañera is a Mexican-heritage right of passage that celebrates a girl’s transition into womanhood on her fifteenth birthday. It is usually commemorated with a simple or elaborate party, or one somewhere in between. It’s akin to a Sweet 16 celebration, but done at 15 or “quince.” [Tribune-Star/Brazil]
Noted in “A Colorado county offers glimpse of America’s future,” Silvia Foster-Frau, WaPo:
As she makes her way to her restaurant each morning, she passes by quinceañera venues, a tamale cafe, a Mexican candy store and shops for wire transfer services. Her customers often greet her in Spanish, standing at the counter below a string of papel picado — colorful Mexican banners — and in front of a menu with a mix of Spanish and English words, advertising items like “chicken nuggets con papas” — with fries.
