The opposite of the Midas touch. A person for whom
everything turns to crap, if (s)he gets involved.
Named after jewellery magnate Gerald Ratner, who infamously declared his proudcts to be "total crap" and wouldn't last much "longer than a M&S {Marks & Spencer} prawn
sandwich", during a speech to the Insitute of Directors (1991).
Although his comments were meant to be tongue-in-cheek, shares in his company drastically plummeted and he
almost bankrupted the company. The speech is often heralded as an example of the value of branding and image over quality.
