1. Celebration of a girl's 15th birthday, marking her "womanhood" and such. Usually huge,
like a mini wedding; everyone dresses up all formally, mariachi band plays, wedding-
like cake, the works.
2. The excuse Latin (especially Mexican Catholic) families use to bascially say, "Hey, my daughter's available now. Do not be afraid to approach."
Mexican Guy #1: "Daaayum, that Rosa looks
fine in that dress."
Mexican Guy #2: "Yeah man, I'm so glad she's had her quinceanera now. Shit, I've been watching her for a year...move over son, watch how
the game is played."
