It's a punishment device bad children in Kid Prison spend hours getting to know very intimately. They get to stand around the prep table smackin the nasty out of cheap meat not fit for dogfood for hours while the House Mother chews their a$$ for not hitting the dead animal properly.
It's only used when there is free meat.
Other times those bad kids get to work on becoming tennis stars with carpet beaters, or scrubbing floors with hand brushes.
