Never heard it used, myself…but some writer claimed it is a mild expletive, south of the Mason-Dixon line.
Anyone ever heard of this?
I’ve spent most of my life south of the Mason-Dixon Line, and I have never heard of “dogwilly.” The closest thing I can think of is “I’ll be dog” for “I’ll be damned.” But there is no willy in there.
Never heard of it. I’m southern as grits.
I’ve never heard of it.
I’ve heard “Whee-doggy” or “Whoo-doggy” as expressions of surprise or amazement, but that’s the closest I can come to “dogwilly.” I’ve never heard it.
Oh, and I was born, raised, and lived my whole life thus far in Alabama.
Moved Cafe Society --> IMHO.
twicks, who as a damn Yankee is otherwise unqualified to be in this thread
You misspelled “Mordor.”
On second thought, maybe not. 
Same here. I’ve lived in Alabama my entire life and I’ve never heard this.
I’ve never heard it, but I’d like to employ it when an opportunity arises. Does one call the coot puttering in the passing lane a “Dogwilly”, or is it used as an exclamation as in “DawwwgWilly! I sure wish that coot would git outta my lane!”
Born and raised below the Mason-Dixon line. Never heard the word in my life. The only result that Yahoo gives when searching for the phrase is this thread.
Same here. Being a born-n-bred Okie, I’m not quite Southern, but at least a kissin’ cousin.
Dogwilly? No, honey. But I will say I’ve heard “willy” used as a euphemism for penis, so maybe someone’s inventing a new insult.
Not a “regular” southern word.
Lifelong southerner, never heard of it.
Never heard of it, but fully intend to find an excuse to use it before the week is out.
Very few people know that the Crack of Doom is actually DeSoto Caverns.
Well, there is “dawg bone”, which is sort of a euphemism for “goddamn”… (I fondly remember a Pogo cartoon in which Seminole Sam is buttering up Albert, who says “Dawg bone!”, to which Sam replies “Dog bone indeed, sir, as you so aptly put it…”)
Never heard it before.
Dog is euphemism for God:o
Dog is a dislexiaism for God.
