In Brisbane and just done a session explaining an Exchange 2010 design and the concept of Database Availability Groups (DAGs) and servers etc etc
This explains the shaking of heads when talking about DAGs!
What does the Australian slang term dag mean?
A dag is technically the matted wool on a sheep’s tail, but in typical usage throughout Australia, it refers to people who don’t have a neat, tidy or cultured appearance. It can also refer to a person who tends to be quite informal.
It is not necessarily a derogatory term in modern usage, but almost always has negative connotations – ie ” He’s a real dag!” or as an adjective – ” His clothes are daggy.” Often it is used in relation to someone unfashionable.
