The sexual act similar to the "Eiffel Tower" in which one female is penetrated from the mouth, vagina, and anus from 3 other men. The Bermuda Triangle can be performed from a number of positions, but the most common is a doggy-style like position with one man behind and one man underneath.
When two men are having sex with a woman; one of the men is at the front end recieving oral while the other is at the back end. The woman is in the doggy style position and the "Power Triangle" is completed when the two men give each other a high five with both of their hands simutaneously. It is called a "Power Triangle" because when it is seen from the side, it creates the shape of a geometric triangle and also because it's fucking awesome.
The "Power Triangle" can be eqiulateral, isosceles, or scalene. This is based on the number of midgets involved.
