A threesome with 1 woman and 2 men. It is important to remember that straight men do not make eye contact while in the act. Doing so will question their sexuality.
Larry: Did you hear that Eric and Brian were in a Devils Triangle with Sarah last night?
Brad: Yeah man, I did, what homo's.
Larry: No man, its cool, they didn't make eye contact.

Get the Devils Triangle mug.
A made up game of quarters with three cups arranged in a triangle. The rules are unknown because the inventor of the game, Brett Kavanaugh, could not explain them under oath.
"Hey Renate? Want to play devils triangle with Mark and I?" Brett asked.

Clearly a drinking game...with three glasses. Have you ever played Quarters? It's like that, except two guys stick their penises into one woman.
Hey do you want to play Devils Triangle?
-Sure, how do you play?
Let's get three glasses and fill them with beer. I like beer. Then we will give all three beers to a woman and stick our penises in her.
-Ffffffuck yeah.

The bad threesome.

In heterosexual jock culture in the 70s and 80s there were two kinds of threesomes. The good threesome involving two women and one guy where all partners are willing, and the bad threesome which involves two guys and one women (usually intoxicated) A guy with two women was considered a stud or player, two guys and a drunk girl not so much. So one penis was considered good (angels) threesome, two penises like the two horns of the devil were bad. This was a very common phrase back in the day, but the term has since been taken up by the swinger subculture, which still use the Devil's threesome and Angels's threesome vernacular.
Hey Man you ever had a threesome?

Yeah, but just the devils triangle.

Are you talking about the good kind of threesome or bad one?

One I'm fine with, the other not so much.

Bad.... but it was OK. Just don't look in the other dudes eyes, and if your second no foreplay.

A drinking game. You ever play that game quarters? You put three cups of beer in a triangle while having a threesome with two dudes and a woman but the two dudes don't look at each other. Then you go to Tobin's house and workout.
"'Devils triangle', Mr. Kavanaugh?"
"You ever play that game 'quarters'?"
