This tweet from The Dignity Project appeared mid-afternoon.
Twitter didn't feel it was all that, well, dignified.
The charity's Facebook page suggests it's struggling somewhat.
BuzzFeed has reached out to the charity for further comment.
The charity has claimed on its Facebook account that its Twitter account has been hacked. It then deleted the Facebook account.
A statement appeared on the charity's website, but appears to have been taken down.
It's not the first time a sexist tweet has appeared on the account.
