[Poohbah]

No wonder I can't understand a darn word they are saying. They are rude too, especially if you are female.

If you can't understand a darn word they're saying, how in the hell can you know if they're being rude or not?

[Canticle_of_Deborah]

Since you are being ever so sweet this Sunday morning, I will rephrase for the more literally inclined.

I can't understand most of what they are saying. The tone of voice, overall manners and few words I can understand are not polite.

Better?

Rude in any language is pretty much apparent.
