Hoon is a great word and thank you for sharing it with us. It has absolutely the right kind of sound to express the intended contempt. I promise to use it each day this week, and when anyone asks me, I will tell them it is ZILD!

Umm... did I miss CapK's evidence that this was a ZILD word first and foremost? Don't ask me, I'm just an innocent (?!) [POM] abroad, but I'd say on the evidence at the moment the national origin of this word remains unproven.

Is CapK more reliable than an internet dictionary?
Is that an insult or a compliment?

Just asking... [running-off-to-hide-from-the-trans-Tasman-flak-emoticon]
