You all ready?
Sometimes in conversational English, when the first part of a sentence is obvious, it is omitted (i.e., not spoken).
In the Blog 008 example when Josh says, “You all ready?” he means, “Are you all ready?” or “Are you completely ready?”
“All ready?” has the same meaning.
In the Blog 010 example when Josh says, "You okay?" he means, "Are you okay?"
Note: An omission is s.o./s.t. that has been left out, or omitted.
