What McDonald's-related term was first mentioned in the Merriam-Webster dictionary in 2003?
In 2003, the term "McJob" made its debut in the Merriam-Webster dictionary's 11th edition, where it was defined as "a low-paying job that requires little skill and provides little opportunity for advancement." The term has its origin in 1990's slacker parlance and was meant to define any entry-level job with lousy pay, but McDonald's executives took it as an exclusive slight against their company. According to Jim Cantalupo, the chief executive officer of McDonald's at the time, the definition constituted a "slap in the face to the 12 million men and women who work hard every day in America's 900,000 restaurants."
