What is the difference between だろう and でしょう?


Basically, the title says it all.

I've encountered quite a handful of sentences with these words, of which
meanings seems to be the same. I'm just wondering in what ways they differ and
how people use them...




でしょう？ is the polite form of だろう？ but the main difference is that, while men
can use でしょう？, women rarely use だろう？ because of how masculine it is(Unless
they're young women speaking to their friends.)

For example, if you hear that the person you like is going to marry someone
else. You reply with 嘘だろう？

In the case of a girl, she would maybe say うそでしょう？

Sorry for my crappy examples haha.
