I grew up in the south in the late 50's - 70's before moving to SoCal.
So it was cool seeing the one's already listed.
I also will not get into racial slurs from the 50's and early 60's.
I also remember
Puttin' "auil" in the car or cookin' with it instead of "oil".
Gettin' "minnas" for fishin' instead of "minnows".
Openin' the "winder instead of "window".
Also Goin' "over yonder" as a distance related to "out of sight".
Why it "ain't" instead of "are not, is not or am not"
Bein' "plum tuckerd out" instead of "exhausted".
Talkin' to "y'all" or "all y'all" instead of "all of you".
