The fixing anything part probably is more common among
male (
U.S.) Southerners. And not all Southern
accents are slow (
Boomhauer from
King of the Hill, for example.) Someone from
the South who's not
ashamed of it.
In response to mcSey, below, I've read novels set in England where "Southerner" was used to mean a wimpy city guy, since the south is where the larger, more sophisticated cities are in England; presumably "Northerner" might have the same vaguely "hick" connotations there that "Southerner" does in the U.S.
In response to mat catastrophe -- well, if you go far enough south, say to Florida, you run into Yankees again.
