weird stuff in scam email

Brie

I do seem to get my share of these.  And as a new fun twist today's warning about a potential security breach and someone hacking my bank account has come (supposedly) from a bank in Brazil!  Normally my scams are from either the US, the UK or (oddly) The Netherlands.  

Anyhoo - after all the usual twaddle about did I request this payment to some bod at some Banca Instituicao (at least that's what I think it's saying, knowing the routine, but not being able to understand the lingo) there is an odd line at the bottom with the following words in English.

second wife thus darkness definition mail next careful mysterious closer perfectly cover history double slip

What's all that about?????

It's a collection of words that aren't associated with scams, in an attempt to fool automated scam detection.

In the early days of spam/phishing emails there was often loads of apparently random sentences and other twaddle like that.
