I live here in the US. I've NEVER heard the term bribe in a neutral or even positive way. It might be used in a mocking way, as if to mock the idea of bribes, but never seriously.
So, unless you are confusing that mocking nature as morally neutral or even positive, this is incorrect.
You've never heard a parent or teacher say they bribed their kids for good behavior?
I also live in the US. It's uncommon, but is used that way sometimes.
