English translation for seigneur c koi cette photo t ki mm?

Answer 1

"Lord! What's this photograph"
(t ki m m?) <-- "t ki" is short for "qui es-tu" or "tu es qui" and even "t'es qui" in spoken french. So... "Who are you"...
I suspect "mm" is for an interrogative "huh" which in french should be written "mmh"... Further you could find "mm" meaning "même" which is translated as "even" (as in "this is even more complex") or "like" (as in "this is like this or that") according to context.
