What's déjeuner de garçon?

Answer 1

It's an expression which was used by a highly respected writer, Prosper Mérimée, in his story: "Le Vase Étrusque"
"Qu'il lui suffise de savoir qu'on en était venu à ce moment, qui arrive assez vite dans un déjeuner de garçons, où tout le monde veut parler à la fois, ..."

I quote this just to show that it is a bone fide French expression meaning a lunch attended just by boys (including big, grown up boys!)

Answer 2

We'd rather say "déjeuner entre garçons", it litteraly means "meal of boys"

Answer 3

Litteraly it means "Boy's meal" but i'm not sure if it's an expression..

Answer 4

That doesn't exist, but it seems to mean that it's a lunch with only boys....
