In Australia, where I live, it is not uncommon for people to describe something as "a bit 'how ya goin''" to mean that it's a little bit dodgy, or not quite right. An example is
"Hey don't you have a new coworker?"
"Yeah, they're a bit 'how ya goin'"
which would mean that the new coworker is maybe a bit weird or not a good fit in the office. I've also heard it to refer to other-than-humans:
"How's the uni course?"
"It's a bit 'how ya goin'"
which would mean that the course isn't going well, but implying that there's a problem with the course itself. I would expect a follow-up closer to "the timetable doesn't fit and the lecturers are terrible" rather than "the course is great but I haven't studied enough".
I had thought it might be connected to/descended from the English phrase "how's your father", but I haven't found any evidence of that and the 'how ya goin' version doesn't have any lewd connotations, as far as I know.
Does anybody know where this phrase comes from, and why it's used in this context? Urban dictionary lists it as Australian slang, but I would love to know if it exists anywhere else. It's a hard one to google, as "origin of phrase 'how are you going'" doesn't yield great results, for obvious reasons.
