As a non-english speaker, I appreciate «Y'all» 'cause it always bug me the absence of a way to reference more than one individual in English.

What you mean «You» is used to reference both one person and a crowd? English is fuck up.

Is the difference between youse and youse guys the number of people involved? Similar to y'all and all y'all?

"Y'all" has wider reach than this map suggests, particularly in black and queer communities.

I’m on the border of y’all and you

I don't think "Y'all" would be problematic. But I also offer "You peeps", I enjoy that one more in day to day conversation.

Where does this put Scott the Woz?

I'm from Maryland and I said "howdy" in New York and I got roasted by the CVS clerk for 2 full minutes. And then I said "do y'all have Tylenol" in hopes that she could point me in the direction. Another minute of her roasting me...

Should be fine 👍

If you live on the line, or move north/west, it's now "you all".

I have a VERY southern friend. He once said "y'all all".

In what context(s)?

Where's my fellow "yo'd'll"s at

I'm surrounded on all sides by Y'all Qaeda send help pls
