MRDA, an abbreviation for Mandy Rice-Davies Applies, is Internet slang meaning "well he would say that, wouldn't he?" It is used to indicate scepticism of a claim due to the obvious bias of the person making the claim.
The source of the initialism 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 (18 years old at that time) made the 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 retorted "Well, he would, wouldn't he?" (often misquoted as "Well he would say that, wouldn't he?")
