Over the past 18 years of doing real estate on the beach I have introduced many people to the Bay of Tenacatita. I start with the basics, "that is tenacatita straight out, then point to La Vena, LA Locos, Punta Serena ending with Boca, the end of our beach. Among other points of interest I mention that we get year round sunsets, saying "the Winter solstice is just to the right of that rock and the summer solstice is just to the left of those upside down little titties". Not once has there been any confusion about where the upside down little titties were (nor any remark about my terminology).
When I first arrived in LM, someone pointed out tenacatita. To make sure I had the word correct, they pulled the front of their shirt out, and repeated, tenacaTITA. Maybe just call it boob bay?
