A Threesome involving 2 girls and a guy. The guy lies on his back while girl A rides his dick and girl B rides his face while both girls kiss, thus completing a triangle. Girl A can also be flipped around so girl B eats Girl A’s pussy while girl A give the Guy a blowjob but this is very physically exerting and not for amateurs.
Bill: I saw you take those two coeds into the bedroom at the party last night.
Dylan: yeah I got them to preform a Thomas Triangle on me before I squeezed my go-gurt all over them

 Get the Thomas Trianglemug.
Get the Thomas Trianglemug. A natural patch of pubic hair. The Devil's triangle runs from the bottom of the waist to the start of the grundle; in other words, it's the part of the crotch that is visible during normal intercourse.

Get the Devil's Trianglemug. Two women spit roasting a man. The woman behind pegs the man with a strap on whilst he eats the other woman’s vagina. The woman can be kissing, high fiving or tweaking each other’s nipples. It’s the opposite of an Eiffel Tower.

Get the Tuna Trianglemug. A sin-ful triangle that continually needs to go for confession so that it could behave more like a right one on this side of eternity—until its last breath when it will be platonically transformed into a perfect one.
