What on earth does "Your all alone" mean?

What is the word "Your" referring to? Your what is all alone? I saw that nonsense posted on here and I tried asking the poster what it meant but (s)he wouldn't explain in a sensible and logical manner. How are we supposed to respond to such a nonsensical post?

It's called a grammatical error.

@ChipmunkErnie Why wouldn't the OP explain it to me? Here is the post I mean:

@KarenKC It appears to be a pun, and it says "you're" not "your"
