I have learned a new word, though I’m quite familiar with the reality. From BBC News – Why your inbox fills with bacn instead of spam:
Bacn is becoming what spam once was – the nuisance that fills up your inbox and makes it hard to pick out the important messages you have to read and which require a reply.
Bacn is all those reminders, newsletters, notifications, limited offers, alerts and other ephemera sent by websites, e-tailers and other services you have used ever since you made your first mouse clicks on the web.
It is called bacn because those messages sit in the middle of a short continuum between what tech folks call spam (fake meat/junk mail) and ham (real meat/real mail). Those messages are bacn because they are not quite real messages but are not quite junk either.
