When people say 'pa respe figi w', does that excuse them so they can say a bad word? Doesn't that mean that 'out of respect for you' i'll tone down what I heard... or something like that? Which means that you can't repeat a bad word after you use this expression, right? mesi davans!

Do you mean: pa respè figi w, orespè figi w, orespè?
If yes, then people say that to warn you that something vulgar is coming.
For example:
Lè'm te pale avè l, li te di'm, orespè figi w, pe dyòl mwen.
When I spoke to him, he told me to, pardon the vulgarity, shut up.
