KOTH is a show that I can take or leave, so I’m not a regular watcher. There’s one character that calls Hank ‘Honey’.
Why?
That’s Joe-Jack. He calls everyone Honey, not just Hank. Regardless of gender.
Why?
It’s my understanding that in parts of the south “Honey” is a general term of affection, not a signifier of love like it is in most other places. Could be wrong about that.
Because it’s funny?
My dad calls all waitresses “Honey”. It’s too late to stop him now.
In Huckleberry Finn, the slave Jim calls Huck “Hon”.
It’s not a widespread phenomenon and I have only heard of one man, my uncle, ever using it as a general term of affection. He’s a pretty cantankerous man on the whole but uses it without any kind of irony for all of his grandchildren and has even called me honey once or twice and I’m very much a guy.
I think the main issue Joe Jack would have with that explanation is that, by and large, Texans don’t consider themselves Southerners.
I second the “it’s funny” explanation with a dash of “Southern/Texan colloquialism” for flavor. Clearly if there were any sexual component to it Hank would be quite uncomfortable with Joe Jack’s calling him “Honey” but Hank isn’t flapped at all by it (although honestly I think for a cartoon it’s kinda hot).
I don’t get this impression at all. I live in Houston and while people would normally consider themselves “Texans”, most people also identify themselves as Southern.
I have never heard a man refer to another man as honey in a heterosexual context. I, too, found this kind of weird.
“Come back to the raft ag’in, Huck honey!”
You would certainly have a better take on it than I would. I’m mostly going by the general feeling of “Texan-ness” I get from KotH characters in general, and the occasional comedian (like the one, [del]whose name escapes me[/del], who said “Texans don’t consider themselves Southerners, because Texas doesn’t want the South. Texas wants Mexico.”)
Edit: I remembered who it was. Jebus help me, it was Gallagher. Please don’t hold that against me.
Not to say there aren’t people who feel that way. Most of the people I associate with just think of themselves as Americans who play the whole Southern/Texan thing up as a bit of a joke. Hell, my Southern accent (I was raised in Alabama until my teen years) only comes out when I am talking to someone expecting it (or I am drunk.)
I own boots, but they stay in my closet until Rodeo days. Otherwise, it is Johnston-Murphy loafers.
Tough to peg down Texas. It is so big and diverse. There may well be large number of people who feel as you suggest.
I think of Houston as being the most Southern part of Texas. (it’s practically West Louisiana) I’m from the deep South and I don’t consider Texans Southern.
You live in Austin. That’s practically Massachusetts! 
Isn’t this the same show where Dale’s wife calls Hank’s wife “Suge” short for sugar.
Texans listen to both country and western.
It is weird to me that this is weird to you.
Nancy calls everybody “Sug.”
