Mimi's "me” (3)
I believe the answer is:
moi
'mimi's me' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for moi that I've seen before include "Daniel arap . . ., Kenyan president for 24 years" , "it's the writer being facetious" , "egoist" , "affected me" , "Just me, monsieur" .)
