This is one that I would hear quite a lot, and I'm sure a lot of more Australian Australians in air quotes would say " You little ripper" but I probably wouldn't use this in my day-to-day language.
I looked at not the ripper suspects, but I looked at the type of person who was considered to be, to have trades that would lend themselves well to concealing body parts or blood on one's garments.
Jack the Ripper, Jack the Ripper, something of a rapscallion, but there are many rippers out there, folks, and since when is it a crime to love your big, beautiful knife?
