What does "uncork deep shit" mean? Is it common to use the word "uncork" like this?
To "uncork" in this case means to "open up", "reveal" or "uncover". "Deep shit" refers to very deep or very personal things. However, this is a more profane way to say this since she uses the word "shit" in place of "things". To "uncork some deep shit" here means that some very personal things are being revealed. It is not very common to use the word "uncork" in this way. She just uses "uncork" here as a metaphor for opening something up, since "uncork" normally refers to opening up a bottle of wine by removing the cork.
