The story says that this red thing (Pompon rouge) gives you Good luck.
That's why some people just steal it in the street from the hat of a sailor. But French women always want to touch the pompon in the street.

On dit que le pompon rouge porte bonheur.
Les marins se font parfoir voler ce pompon dans la rue.
