Ay, you did wish that I would make her turn:
Sir, she can turn, and turn, and yet go on,
And turn again; and she can weep, sir, weep;
And she’s obedient, as you say, obedient,
Very obedient. Proceed you in your tears.
Concerning this, sir, – O well-painted passion!

– William Shakespeare

Othello, Act 4, Scene 1. When Lodovico protests that Othello should call Desdemona back to apologize after hitting and dismissing her, we get this muddled speech in response. Othello’s deteriorating mental state is reflected in his disjointed language. He doesn’t seem to be able to properly articulate why he is so upset. He appears to suggest that Desdemona is available for sex to any man, including Lodovico. He dismisses his wife’s weeping as "well-painted passion" or fake tears. He is speaking here to Lodovico, while also talking to Desdemona, and not making a great deal of sense.
