by imbal's iron pizzle!

I’m reading some old school fantasy- the goblin tower by l sprague de camp– and loving the ludicrous curses. Imbal seems to have been made of metal, for he is also possessed of a bronzen arse and brazen balls (though that might just mean they’re a bit rude or forthright, leaping out in public and loudly proclaiming their right to do all the things balls do).
