I think that “all” is evolving in this direction. It was already used as an explicit pluraliser for “you” (alongside “guys”, -s, and others); and now I’m seeing “they all” more and more across the internet, even in situations where the “all” clearly does not convey “every single one of them”.
Just keep in mind that this is anecdotal from my part, not backed up by hard data.
Do we currently have an explicit pluralizer for they?
We can thank Harry for this one
