Does the suffix "some", when it comes after a number, conjure up some kind of an orgy?
Here is an example:
Have you heard that Jim and Tina made up a foursome with Jean and Bruce?
would you ever ask such a question from someone you barely know (considering that you just assume he or she has some idea of what you're talking about)? In other words, is the risk of misinterpretation subtle enough for you to take?
Here I'm not taking into account those who have a so-called "dirty mind" and tend to interpret everything their own way. Instead, I'm interested to know how the majority of English-speaking people (especially those of the United States) would interpret that.
