Immense!
I'd like to imagine it means "I know, right?"
Which tells us nothing of what the 'doodle' in Yankee Doodle Dandy means. Yankee fine; Dandy, a foppish hipster type; Doodle???
Not sure why the author of this article couldn't be bothered to complete the etymology he started.
I submit that this definition is as true today as it was in 1887.
Seriously, a science teacher in high school read that definition from a dictionary, and handed out photocopies of it to my class, in the hopes that it would discourage us from using the word, because he got sick of hearing it. It had the opposite effect, obviously.
...but anyway, that's why I laughed when The Stranger in The Big Lebowski implied, with subtlety, the same meaning when he said it was a name "no one would self-apply" where he came from.
I'm sticking with "hairy horse anus."
