What does humpybong mean?

Oh, dude, "humpybong" is actually a place in Australia, not some weird slang for a bumpy camel ride or a dance move from the '90s. It's a suburb in Queensland, so if you were expecting something more exciting, like a secret code for a wild party, sorry to disappoint. But hey, now you know a fun fact to impress your friends at your next trivia night!
