"They Go Off Like The Proverbial Frog In A Sock"

Kylie discusses her North American tour, but then uses Australian Slang to do so:

1. go crazy, be raging; 2. (of a party, dance party, etc.) be excellent; be successful; fire; 3. (surfing) produce many good riding waves; really pump; 4. (of an illegal establishment) be raided by the police

I've never heard of any proverbs with "The Proverbial Frog In A Sock" (and somehow I hope I never do).
