Bacn is a new term for any email you receive that isn’t spam but isn’t a personal message. For example, an electronic bill that you get through email is bacn. It’s been Web 2.0-ized so it’s not spelled bacon, it’s bacn. I just don’t like that it’s pronounced “bacn.” It should be pronounced “back-en.” I think it’s more fun this way. What else is pronounced “back-en”? Maybe you’re cool and say “backing up,” backin’ up because you think that the last “g” is useless and overkill.
