Is this arrangement a foursome or not?

Inspired by another such question, now I’m wondering about:

Two couples going at it simultaneously in adjoining rooms that can hear each other. (Regardless of gender/orientation. Any two couples.) Do they constitute a foursome (a.k.a. ménage à quatre) or not?

Nope, just a bit of exhibitionism and/or voyeurism.

Ah, memories of the B&B we stayed in in Ireland on our honeymoon. We awoke in the middle of the night to hear the couple on the other side of the (paper thin) wall going at it- the young lady was quite vocal. So we made the best of it and joined right in, but safe in our own room. We passed each other in the hall the next morning on the way to a late breakfast.

Nope. It doesn’t become a foursome until they swap partners or get into a group formation.

Nope. Definitely not.

Maybe if they arranged it beforehand. But probably not even then.

Not unless they play golf together afterward.

Reminds me of prom night.

Are they playing Bridge?

Inconclusive. I’d need several pictures at varying angles and lighting amounts to make a full determination. Video would be even better.

I dunno, man. Footage of Bridge games tends not to be terribly exciting.

This.
It’s only a foursome if they are all together, either swapping partners, with their own partners, or in a big heap.

A foursoem requires that at least two people ‘touch’ two other people, or one person that touches three other people. One guy with three girls is a foursome, one girl with three guys is a foursome. Two couples together only become a foursome if at least one girl and guy cross over, ideally both cross over.

What if each couple senses that the other has entered into a tacit agreement with them—and via their sounds they start to influence each other…

I had in mind a male-female couple in one room and a female-female couple in the other. Tacitly cooperating through sound.

Kinky but still not a foursome.

I am fairly certain Bridge has been rule 34’d, but I don’t care to research it.

I can’t see any possible way that would be considered a “foursome.” I mean, I wouldn’t even consider it a foursome if they were in the same room. Imagine, say, a college situation where both beds are occupied with couples going at it, but no other intermingling. I really doubt anyone would claim they participated in a foursome in that case.

Not even remotely. If it all it took was hearing people, then I’ve been in plenty of situations that were orgies.

…and 4 no-trump could be very disappointing.
