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.
(Note: Again, this is not in alphabetical order but in this case, these two words, cove and cuffin, are placed together before crack and cracker in Cassidy’s book, so I have followed his order here.)
Cuffin is a cant expression similar to cove. It is believed to be derived from cove or related to it in some way. Cassidy suggests that this comes from caomhán, an obscure diminutive of caomh. Again, the pronunciation is wrong (keevawn) and there is no reason to suppose that there is any Irish connection. Also, cove and cuffin mean a fellow, a man, not a friend or pal or beloved person.
