As mentioned in the post Puerto Rican Spanish Slang for Penis: A Bug or a Guy’s Dick?, a completely innocuous word in one country may mean something seriously crude in another. This time the word is concha which in many countries has the sole meaning "sea shell."
Above, I stand in front of the sign for the Hotel La Concha. Obviously since the hotel is named La Concha we are talking about the innocuous concha translation in this case. The name for this hotel makes even more sense when you learn that it is located on the water, and one of the hotel's main structures is in the shape of a sea shell that looks out on the Atlantic Ocean. There is even a sea shell drawing in the hotel's sign. So, concha meaning "sea shell" makes perfect sense here.
Yet, tons of Latin American tourists do just as I did here; take their photo in front of this sign. Why? Well, la concha also happens to mean a woman's cunt or pussy. So for many Latins, they are standing in front of the Pussy Hotel, part of the Renaissance chain of hotels.
Before you start throwing this word around, if you are in Argentina, Bolivia, Ecuador, Peru or Uruguay, you might want to keep your voice down.
