It is the tone and level Southern men talk. A deep, soft mumble that is exactly the right frequency of pert near any back ground noise taking place at the time. How many times have I had to ask a guy to repeat himself?!
And this is just the opposite for Southern ladies.
One of the thing the list missed was a lady using the phrase "Bless his/heart", it usually means a blistering remark is coming.
As in " Bless his heart" , he could eat corn off the cob through a picket fence.
You could add: "prid near, "shood oughta", "stiddy", "might cood". Or the every popular, Cajun "Wher' we be go now?"
