From what I gather, Okuu has realized that her spelling is so horrible she's just offended her master. She can't tell her γ from her γ‘, and this has spelled Satori's name, γγγ¨γγ, as γγ‘γ¨γγ (Chitori). She probably misspelled the honorific γγγΎγas well, writing γγ‘γΎγγ. Unfortunately, I have no idea what it all might mean. Maybe slang?
Orin's just trying to ease the mood... And not succeeding either.
