A sexual reference of the ever-popular, possibly fictional "Bermuda Triangle", which has to do with a state of mind after having a threesome with your partner and another stranger. (This has nothing to do with the Bermuda Triangle)
Jack: Dave, where were you last night?
Dave: Oh dude, last night I had the best sex last night. I fucked my girlfriend and her friend last night. It's literally the best of both worlds!
Jack: Denial is not the river in Egypt I guess, it's in the Bermuda Trifecta.
