Why is it called dumb luck?

Bad luck is bad luck.

Why use shit to describe it?

Because shit is the most smelly shit people often say, bad luck is described as shit.

Foreign English: Shit, it may also have something to do with this. Shit = shit, when something happens in a foreign country, say "shit". When it reaches China, it is used to describe luck! ! !

Please forgive me.
