Help Me!

well out of the context it seems a bit hard to explain, as i don't know what she spoke about
But i can translate it, if it's well-spelled
Declaration means declaration (that's not to difficult)
mère=mother
maire = mayor
so it must be something by her mayor or mother... but there's another solution... because that way it doesn't sound french.
It might be that you've forgotten a `d` in the word "mere" but as it is a vulgarity i won't translate it literaly
and it would mean "stupid worthless declaration".

It makes sense: You need an official declaration from the mother of the two little girls in order to take them any where.
