Tony Massarotti — a popular radio host who was suspended last year for an insensitive joke about black people — has come under fire again … after he muttered a racial slur during a live broadcast.

The latest exchange occurred on Wednesday’s episode of “Felger & Mazz” – a Boston afternoon drive show – when Massarotti was talking to his co-host Michael Felger about his concerns about Generation Z.

The former Boston Globe sports writer said he believes the Z in Generation Z “stands for Z*****head” – a term often used to insult people of Asian descent.

Felger chuckled briefly and cringed at the comment… but the conversation continued anyway – without elaborating on the remark.

Not long after, social media users called for Massarotti’s job – saying it was the second time in the last year that he had made racially insensitive statements on his show.

If you’re not familiar, back in February 2023he warned Felger to be careful of two black men sitting behind him: “Because the last time you were with a bunch of guys like that, they stole your car.”

A short time later, he issued a mea culpa, claiming he wanted to “make fun” of Felger, whose car had reportedly been stolen in New Orleans just weeks earlier.

Nevertheless, Massarotti was suspended without pay for the rest of the week.
