The 3ed hole found on the side of the stomach of a woman. It's function is the same as a vagina except it does not excrete urine, but can still cum and can have an orgasm. This third hole is visible only after maturity, and if it is not yet visible, it is just under the skin waiting to peak through.The phrase "fuck me sideways" comes from this Latin word.
On Indian women, this hole is not found on the side of the stomach, but is found on their forehead. The ugayllaa on the forehead is normally covered by a red dot. In this situation, it should be called a mangayllaa.
The man fucked her sideways in the ugayllaa.
