The small hole, shaped like a triangle located only under a woman's nice tight ass, in between her legs. Only noticeable at the precise moment when her thighs touch, creating a hole above the touching thighs, and under the ass, through which you can see in front of the lady in question. Some men are said to get lost there.
"Hey Tim, Sarah is wearing those tight yoga pants again, look at that Bermuda Triangle, you can see the photo booth from here."
