as an athlete can suffer a blown shoulder or a blown knee, a competitive drinker can suffer damage to their kidneys, resulting in said kidney being " blown " out
Malachi : I participated in the 11 day Drinkathon sponsored by Hezekiahs Porno Dungeon and I suffered a blown kidney on day 9. I've been recuperating at the Anheiser Busch treatment center.
A Douglas Adams original, was used multiple times in his book "The Hitchhiker's Guide to the Galaxy". Usually (but not necessarily) following "a load of", dingo's kidneys means rubbish, bollucks, crap or bullshit.
Seriously? I have to give an example in a sentence? I can't just leave it blank? WTF?! That's a load of dingo's kidneys!
