You must prepare your bosom for his knife,
said Portia to Antonio in which
of Shakespeare's Comedies? Who killed his wife,
insane with jealousy? And which Scots witch
knew Something wicked this way comes? Who said
Is this a dagger which I see? Which Tragedy?
Whose blade was drawn which led to Tybalt's death?
To whom did dying Caesar say Et tu? And why?
Something is rotten in the state of Denmark - do you
know what this means? Explain how poetry
pursues the human like the smitten moon
This is from Shakespeare’s play  Julius Caesar .  It means “You too?”, the horrified question asked by Caesar when realising that one of those who had stabbed him was his friend, Brutus. The phrase has come to refer to betrayal of trust.
