A New Jersey high school asked girls — but not boys — to take a pledge to refrain from cursing, reported northjersey.com.

Lori Flynn, the teacher who launched the pledge at Queen of Peace High School, said, “We want ladies to act like ladies.”

Timothy Jay, professor at Massachusetts College of Liberal Arts and the author of Why We Curse, said that people swear between 80 to 90 times per day on average but that pledges “NEVER work,” reported the news outlet.

One male student said, “It’s unattractive when girls have potty mouths,” although he himself admitted to cursing while playing baseball. Some of the girls appeared to support the ban, with one believing the pledge was a “good idea” though difficult to put “into action.”

The school has even distributed pins with a pair of lips slashed with a red line.

After the pledge took place, Flynn reportedly said, “Gentlemen, you are not to swear in the presence of ladies.”
