Its official: OK, boomer is now part of the U.S. Supreme Court record.

Chief Justice John Roberts dropped the retort Wednesday at oral argument in an age discrimination case, asking hypothetically whether the use of that phrase could be considered evidence under the Age Discrimination in Employment Act.

In the case before the court, Noris Babb, a pharmacist for the Department of Veterans Affairs, contends she was denied promotions due to her age and gender.

Roberts imagined an exchange during the job application process.

Lets say in the course of the, you know, weeks long process, you know, [there is] one comment about age, Roberts riffed. The hiring person is younger, [and] says, you know, OK, boomer once to the applicant. ... Is that actionable?

His scenario was met with laughter in the courtroom, as the official transcript for Babb v. Wilkie noted.
