A sexual position, plot, or game with unknown, but most assuredly nefarious connotations according to people on the left. Also apparently an innocent drinking game in actual reality.
Did you read Brett's yearbook entry about that drinking game Don? Don't tell me Devils Triangle is a drinking game Chris, we all know it's a code phrase for an insidious sexual act or other horrible unspeakable perversion. I have extensive knowledge about such things.

Hey Squi you wanna play some Devils Triangle? I got the quarters if you get the Pabst Blue!

Get the Devils Triangle mug.
A nickname for the Bermuda Triangle. Or an actual fucking drinking game. Modern definition has apparently been changed to a threesome with 2 men and 1 woman. Tbh I don't know what's going on anymore in this world.
Example 1:
Frat Boy: Hey bro, wanna play Devil's Triangle?
Random Feminist: You're perpetuating rape culture!
Frat Boy: I just wanna get drunk...
Example 2:
Guy: Hey did you watch the new documentary on the Devil's Triangle?
Random Feminist: You're perpetuating rape culture!
Guy: I just wanted to learn about the Bermuda Triangle...

Get the Devil's Triangle mug.
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.
I love your Devil's Triangle.

Get the Devil's Triangle mug.
A term for a three way with 2 men and 1 woman that couldn't possibly be a game or anything else becuase words only mean one thing.
Can also be a metaphor for people believing what they want to be true.
Regular person: Have you played that strategy board game Devil's Triangle?
Partisan autist: No that can't possible be a game because it's already a sexual practice.

Get the Devil's Triangle mug.
A drinking game played at parties by 2 men, in which three cups are arranged in a triangle and filled with beer. (Players must like beer.)

One player flips a quarter while the other calls heads or tails. The three drinks are then roofied and handed out to female party-goers. Players then simultaneously rape the first woman to pass out. The coin flip determines who takes anal.

At the moment of climax, players give each other a high five and maybe hold hands there for a bit (optional). Technically the rule is that players cannot make eye contact during intercourse but we all know they do it anyway.

Pretty gay imo
"After working out with PJ and Squee, Brett and Mark went to a party and engaged in a game of Devils Triangle."

"I can't believe you bragged about having a Devils Triangle in your yearbook bro! Everyone's talking about what a homo you are."

"The 'honorable' Judge Brett Kavanaugh perjured himself a bit when questioned about the Devils Triangle. Just a bit though imo."
