For some time now, some of my on-line friends have advised me to provide a version of CassidySlangScam without the invective aimed at Cassidy and his supporters. In response to that advice, I am working on providing a glossary of the terms in Cassidy’s ludicrous book How The Irish Invented Slang with a short, simple and business-like explanation of why Cassidy’s version is wrong.
The word dork first appears in America in the 1960s. It is believed to be a euphemism for dick, meaning penis and by extension, stupid person.
Cassidy claimed that this word comes from an obscure Irish word, dorc, which is defined by Ó Dónaill as ‘lump, buttock; lumpish person’. Cassidy defines it as ‘a small, lumpish person; a midget, a dwarf’ but doesn’t say where he got this definition from. Dinneen doesn’t mention this word, while Dwelly says that it means ‘a piece’. It is highly unlikely that this Irish word is the origin of English dork, mainly because the 1960s is very late for an Irish word to appear in English.
