Dumb
"Everyone agrees that using the word "password" for a password is pretty much the dumbest thing you can do."
Nope!
Inserting your sensitive body parts into a meat grinder beats that.
If you limit the scope of the conversation to IT things, then giving remote terminal access to some con artist who phones you up to tell you that your PC has a virus also beats that.
In both my examples you are definitely going to get hurt.
Using password as a password only means that you may get hurt.
