I have rarely heard it in the last 25 years, but there is a current television program named Bitchin Kitchen. The presenter is Canadian and the program is produced in Canada, but she speaks with a mock New Jersey/Long Island accent.
Every time she tastes her culinary creations, she uses "shcoff" rather than "scoff". The show has survived for at least three years and is probably in syndication around the world.
So maybe scoff will make a comeback.
