No, b***h shield, as in, shutting you down.
Anyway, it involves integrity.
Well, women have to have b***h shields, right? You know, why are some women b***hy and testing? Like, what are women testing? They're testing your intention and integrity. If you have integrity, the b***h shield is bulls**t--you won't have to worry about it.
If you don't put up with their bitchiness in the right ways, you've passed the test, displayed your integrity (that you won't accept bullshit behavior), and... well, gg man.
