short for quinceañera: a big 15th birthday party popular among hispanic families, it celebrates a girl's coming of age in much the same way a "sweet sixteen" birthday does in some anglo cultures, but is usually more elaborate - a combination of sweet sixteen, Catholic religious ceremony, and debutante ball.
