> [@Senegoid](#): > > Sulcus is a general term for a crease or furrow. It commonly refers to the creases and furrows on the surface of the brain. It can also refer to the part of the human female anatomy commonly called “cleavage” (intermammary sulcus) And I always called that the “Interboobical Groove.” ---

Sometimes using antiperspirant under there will decrease the sweating/moisture. If you are a diabetic, you may need better control of your glucose (which can encourage fungal growth that can also be part of the problem.) ---

I don’t know where it came from. We used to talk about it when I was a teen… In the mid 80’s…How to layout and get a tan without getting butt smiles, especially tough in a tanning bed. ---

Sometimes using antiperspirant under there will decrease the sweating/moisture. . . So I’m not the only one. Another thing to do is, occasionally, when you’re alone, press a fold of the shirt you’re wearing into the crease. I tend to sort of shrug it in there with the backs of my wrists. It helps keep it dry on hot days. Then there’s always talcum or baby powder. One of my friends was told to try wearing her husband’s used t-shirts, to colonize her skin with different microbes. It worked for her, but now that I think about it, I’m wondering if they got tucked in and if that didn’t contribute. ---

OP here. Same situation last night, and I pointed out, with great pleasure, the woman’s gluteal sulcus (should that be sulcii in plural?), and I gave credit where credit’s due. I love me my SD. Last time, they were jorts, which I had never heard of. This time, my wife sort of raised my vocabulary ante when she said they were “janx.” Has anyone heard of this word/article of clothing before? Jeans-shorts top with spandex from waist down. ---
