When you make "falling out" plural, which word receives the "s"?
Apparently both forms are acceptable, but I'm wondering which one you prefer using (and why)?

"Fallings out" or "falling outs"? Or would you expand the phrase to something like "times we've had a falling out"?

Answer

I prefer "fallings out", because it is the fallings which are plural (what are "outs"?).  Technically "falling-outs" is also grammatically correct, but I would never use this form because I have an irrational hatred of hyphens.

Answer

I think that both are acceptable while I don't use fallings out.

Answer

"Fallings out". The use is rare though. 
BTW that's a rule for all phrasal verb nouns.
"Comings in and goings out." Still quite rare.

Answer

I could see myself using every one of them, and more possibilities besides.

Answer

I think it would be "times we had a falling out", but with the way that phrased is used in America, it means something final. You wouldn't have another falling out with the same person :)
