I'm well aware that Durex is a brand name in Australia of what we call Sellotape in the UK.
I subscribe to a "Word a Day" mailing list and today's word is Durex. Interestingly, for the Oxford English Dictionary, it only lists the Australian sellotape meaning.
But what made me laugh was the etymology:
"Etymology: < the name of Durex Abrasives Ltd., U.K.-based company formed in 1929 by several U.S. manufacturing companies (including 3M), to manufacture various branded products (including Durex cellulose tape and Durex masking tape) for international markets."
The thought of Durex (in the UK "condom" sense) being manufactured by a company that manufactures *abrasives* brings tears to my eyes ;-) Sand-coated johnnies for extra sensation?
