What does 'Dagnabit' mean? I remember Walter Brennan used to say it all of the time.?

I think it is a saying for "damn it" which was a bad phrase back then.

It means darn or dog gone it or Well I'll be. Dagnabit is probably an earlier curse word that was allowed. Not at all like today's television

It mainly means "Oh darn.", but can mean other things along the same line.

It's the polite way of saying, "Damn it" without it considered to be swearing.

the same as galdarnet, and it's an old peoples thing you wouldn't understand it youngster !

My papaw says that all the time.

It's another way of saying God dammit. It isn't much more polite though.

What about dog gone it???? What the hell does that mean????

these made up words are euphemisms for curses .... or "cus words"
