“Way past” is a way to emphasize that you are ready or which ever verb comes after the phrase.
So, “Are you hungry?”
“I’m way past hungry. I’m starving. I haven’t eaten since breakfast and it’s 9 pm.”
Depending on the context of the situation, the speaker can be showing excitement or annoyance.
“Are you ready to graduate?”
“I’m way past ready. I hate school.”
“Are you ready to go on vacation?”
“I’m way past ready. I can’t wait!”
