Cardi B's attempt to cash in on the catchphrase "okurrr" was reportedly rejected by the U.S. Patent and Trademark Office, which ruled that it doesn't deserve a trademark.

According to documents obtained by the Blast, the phrase falls under a category of "widely-used commonplace expressions." The USPTO also found many instances of okurrr which was part of the justification to deem the expression as common. Cardi has said that she started using the phrase after hearing Khloe Kardashian use it sometime in 2016.

Officials also told the Blast that the phrase "is a slogan or term that does not function as a trademark or service mark to indicate the source of applicant's goods and/or services" and that it does not stand apart from other similar marks.

Okurrr's roots can be tracked years earlier to season six contestant Laganja Estranja, who used it first on "RuPaul's Drag Race."
