A threesome involving 2 men and 1 woman. Generally one man on each side of the woman who high five after achieving climax, creating a "triangle" type figure.

Or, for Brett Kavanaugh, a drinking game with 3 beers placed in a triangle that utilizes quarters.
Bro, that devil's triangle was crazy last night! I think our quarters might've accidentally touched.
