were shy
that is a very literal translation, but you need to give its background. I think it is about a fire that broke out in a public bath(Hammaam). Those who were shy to go out naked died and others who were not shy survived.
Here it is used figuratively."

timid
The full title is a colloquial proverb as has been mentioned too. Interestingly, it is used for opposite situations. People say it about people who suffer because they were shy or timid. It is also said when people act boldly without caring about other people's views or consequences.
I would take some freedom with translating the title. Watching the film of course helps. I haven't.
Here are some suggestions:
The timid get/are gutted.
The shy get a black eye.
Act shy, get a black eye.
Good luck.

اللي اختشوا ماتوا
When someone is outrageous, they are met with the sarcastic "those who were modest, died," implying that there are no modest people left.
