A left-handed person:nothing wrong with being a molly dook...
The book is a postmodern tragic comedy about a sweet Californian dreamer who meets a mollydook mystic in a sleepy village on the North Coast.
Evatt was a left-hander with the bat — a 'molly dook' — and thereby, said the cruel, there surely hangs a tale.
The camera catches mollydook Frank Watts having a crack at the ring, the expressions on his mates' faces recording their ideas of his chances.
Origin
1930s: from Molly (pet form of the given name Mary) or from the slang term mauley 'hand' + -dook representing a pronunciation of duke (sense 2 of the noun).
