I don't speak Spanish, but I've picked up a little bit along the way. A Hyundai Tiburon drove by a cab stand and I said the car is okay, but why does it have a nonsensical name? A Mexican-American driver said it means "shark" in Spanish. I had absolutely no idea. I thought the good folks at Hyndai had tried to invent something! Does anyone know about the Buick LaCrosse in Montreal, or the Chevy Nova in South America?
I've been using tiburon on the radio lately. We have some yellow taxis, some blue, and some white. When business is slow drivers will identify themselves as "el bandito azule" for the blue ones, etc. One guy has the ID "el mejor", meaning "the best", on account of getting long rides. When I hear these IDs, I'll say (please forgive the spelling), "Jo soy el tiburon!"
On a related theme, I remember when a Mexican driver taught me to say, "How are you?" He said, and again please forgive the spelling, "Comme es ta, culo?"
I said that to a few drivers, but thankfully not to any Mexican customers, before somebody explained that it means, "How are you, asshole?" The joke was on the gringo.
