What does "because why not" mean? [closed]

Solution 1:

This phrase is used as an argument (usually by someone who is for doing something). Consider the following:

A: But why would we do that? I don't see how we gain much.

B: Because why not?

B is arguing that instead of looking at the reasons to do something, they should instead be looking at how little they have to lose.
