what does that mean?

It's a gardening term. Don't rake newly fertilised ground.

I believe it is US (American) "gangsta" or "ebonic" (black slang) dialect.

We don't give a **** = We (emphatically) do not care

where = same as normal English

dem = those

hoes = whores = women (widely considered to be insulting - "whore" means "prostitute" in regular English. "Ho" is a term used in the deeply misogynistic (woman-hating) "gangsta" culture)

"Where someone/people [is/are] at" can mean where they are located, or what they are thinking or doing or planning or about to do...

Thus:

We don't care where those women (or girls) are.

Or

We don't care what those women (or girls) are doing.

We don't care what those women (or girls) think.

We don't care what those womens' (or girls') opinion is.

More context needed, really...

Sounds like it's from a rap song maybe?

thank u very much
yes that's from this song
"teaser" by akon and kardinal offishall

It distresses me that foreign kids are using RAP songs to learn English!!

why? do u have a better suggestion?

I believe it is someone who is so poorly educated that ebonic's seems like the queens poetry by comparison
