In 1940 Carole was under contract at Hal Roach Studios. Her career was taking off and she had been given leading roles in One Million B.C. and Turnabout. Hal Roach decided to give Carole the nickname "The Ping Girl: Because She Makes You Purr". The idea came from an automobile ad slogan that said "change ping to purr". Carole hated this nickname probably because the word "ping" was also slang for a male erection.
When Hal Roach threw a party at Ciro's to introduce "The Ping Girl" Carole refused to attend. She said "I was never consulted about the scheme nor do I approve the appellation they would like to inflict upon me. For these reasons I will not be present at my own reception to ping, purr, or even coo." Carole even sent letters to all the newspaper editors to complain. She wrote:
Carole also asked that the newspapers not publish any more of her bathing suit pin-ups. Her protest got her a lot of attention and some critics thought it was all just a publicity stunt. Luckily for Carole the press rarely mentioned "The Ping Girl" after 1940. She was later called "The Chest" but she didn't like that sexist nickname either. During the war the soldiers affectionately named her "The Blonde Bomber".
