Les Six (pronounced "Le sees") is French for "The Six". Les Six were a group of six French composers who were friends around the year 1920. They were young at the time, and they shared a lot of ideas about music. The composer Erik Satie called them "Les Nouveaux Jeunes", but then a man called Henri Collet called them "Les Six" in an article he was writing, and that name was always used for them after that.
