-a-rooney suffix: Is it widespread and where's it from? [arooney]

[gilesalban]

I've been wondering about the suffix -a-rooney.

My family and friends use it from time to time for some expressions such as "yawn-a-roony" to imply that something is boring, but does anyone else use it?

I've seen a user here called Pickaroony, which makes me think that it might be more widespread than my local group. Does anyone else have any examples of it or know where it might have come from?

Thanks if you're able to help.

G.
