The Wife Acceptance Factor is the number between 1 and 10 applied to electronic devices that get brought home. This number relates to how understanding a spouse is about it's usage and, indeed, it's very presence.
Eg: "With my lighting controls not working, the W.A.F. on my my home automation system is at an all time low"
Manpuss: Hey! Don't say that. That is offensive to me!
Bro: Why? Are you gay?
Manpuss: No, I am not.
Dude: W.A.F., man.
Bro: True. True.
Manpuss: Whatever, you racists.
Bro: W.A.F. for days.
