A Nigerian term works very well here to describe white people who react irrationally at seeing Black excellence and joy.

“bad belle”

Someone literally sick to their stomach with envy and hatred watching another shine. What do you call “bad belle” in your language or culture? https://twitter.com/asteadwesley/status/1320430470585344003

“Belle” in bad belle (pronounced beh-leh) is “belly.” Bad belle is a rotten stomach, bellyache, the visceral roil and agony of a stab in the gut when you see something that just rips you up inside. Bad belle is how Peggy Noonan feels watching Kamala Harris being Black and great.

White folks suffer wild levels of bad belle faced with Black genius like @tressiemcphd and attack her mercilessly for their agony. You see them just SICK with irrational rage at her brilliance, fame, likability, joy, success, coming at her Every. Single. Day. with new nonsense.
