This is the perfect way to insult someone who does not speak French. If a guy is being stupid and yet thinks he is being suave (it happens frequently, believe it or not), simply turn to a friend and say "C'est un ours mal léché!" Since French is such a romantic language, he'll think it's a compliment, especially if you pretend it is. The look on the guy's face is quite satisfying when - and if - you decide to tell him it means "He's a big oaf."
