Aunt mav, are you getting a bit behind the times in your old age?
I think I know what getting scratch means, but I'll leave it for someone who is sure. Peeling out: heck, yeah! I've heard that all my life. I'm a South End girl, where we like to drag race down neighborhood streets. If you peel out, you hit the accelerator hard enough to at least make the tires spin in place and squeal, and perhaps even peel some rubber off them as you depart. One alternative is burn rubber.
