BBC Sport is being accused of plagiarizing a phrase trademarked by a Black woman.

The British broadcaster recently unveiled a series of advertisements to empower female athletes. One of the ads features runner Dina Asher-Smith with the words “slay in your lane” printed behind her. The phrase is also the title of a self-help book written by Yomi Adegoke and Elizabeth Uviebinené.

Adegoke called BBC out on Twitter for stealing her words, according to The Drum.

"Imagine being a white woman creating an empowering women's ad campaign for BBC Sport and choosing to rip off the trademarked name of a book specifically aimed at uplifting black women, in an almost identical font,” she wrote.

The writer said she contacted the company to check them about their thievery but "nothing had been done."

The phrase is classified as a registered trademark in the United Kingdom, meaning it cannot be used for promotional purposes.

BBC has not spoken publicly about the issue but James Cross, a member of BBC’s creative team, accused Adegoke of bullying in a now-deleted tweet.

“Your complaint is being looked at, going after innocent individuals on social media won’t speed it up,” he reportedly wrote.

Adegoke believes BBC assumed she didn’t go through the proper channels to protect herself.

“I don’t think the BBC thought we’d have the brains or acumen, as two young, black women, to think to trademark that phrase to begin with,” she told HuffPost UK.

“I definitely think they just assumed that we’d just stumbled across something that was catchy and smart – but we wouldn’t have the sense to do something about our intellectual property, to safeguard us against this [trademark infringement].”

She also believes the borrowing was a display of arrogance.

“I also think there’s an idea that we’re supposed to feel grateful to occupy certain spaces and be acknowledged, made visible by big organisations; even though it’s the opposite – erasure,” she continued.  “There was a misguided and nonsensical belief that we’d somehow we flattered.”
