'MRDA' an abbreviation for Mandy Rice-Davies Applies is Internet slang meaning "well he would say that, wouldn't he"? - Used to indicate cynicism of a statement of fact due to the obvious bias of the person stating the fact.
The source of the acronym comes from The Profumo Affair, a 1963 political scandal in the United Kingdom. While giving evidence at the trial of Stephen Ward, charged with living off the immoral earnings of Christine Keeler and Mandy Rice-Davies, Rice-Davies made a quip for which she is now best remembered. When the prosecuting counsel pointed out that Lord Astor denied an affair or having even met her, she replied, "He would, wouldn't he?" (often misquoted as "Well, he would, wouldn't he?" or "Well he would say that, wouldn't he?").
