Murphy's Rape
If it can go wrong, not only will it, but it will go so wrong you start to think "This couldn't possibly be happening to me, I must have lost my mind and am imagining this, please pass the thorazine."
Having had a terrible day that not even Murphy's Law could begin to describe I jokingly said the phrase Murphy's Rape. My friend finding it funny suggested I upload it to Urban Dictionary, but as Murphy's Rape would have it, the computer froze when I tried to take my friend's advice.
