Not mine but I did this one in the Guardian today on English dialect words. On finishing I was thrilled to learn I was a WOMBAT: Waste of Money, Brains and Time, which seems a bit unfair, to the wombat.
I do not know if Mr. de Boinod is the author of this acephalous anti-marsupial hysteria but he is at least associated with it; perhaps a
serendipitous koala once shat on his head in Wallamaloo.
My score was so low that the median inebriated wombat would have done better, as I hope you do if you try it.
