Who is Mommo?

Dress code: Like Mommo choose your family! I have been very puzzled by this note on a party invitation from a friend in France. My first thought was it could perhaps be a reference to the book 'Momo' by Michael Ende, oddly enough the first book I ever read in Spanish. Around the time I read the book, I made friends with a Japanese girl named Momoko, or Momo for short, in my Spanish class in Bilbao. Thirdly, after doing a Google search there seems to be a Turkish film out recently with a double 'm' spelling, but none of these ideas seemed right.

As it turns out I had the wrong movie. Were I French I might have caught the reference to the film called "La vie est un long fleuve tranquille" (Life is a Long Quiet River) a popular comedy from the 90s. I think I would need to see the film before being able to decide on my 'costume,' however I unfortunately will not be able to attend. I did go one year to what I will call the 'hottest' party of my life at my friend's mother's house in a small town outside of Lyon. It was the summer of the heat wave and temperatures were + 50 C. I remember spending most of the time in their pool.

From the invitation I also deduce that PAF means something like BYOB only in this case according to your family you choose to bring a bottle or a dish of something to eat. Parties are definitely more interesting with a theme...
