Shadendorphin

n. G. fr. damage + (ISV endogenous + morphine) (2020) 1 : an exhilarating chemical release in the brain that produces a slightly embarrassed feeling of joy on one receiving the comeuppance they so richly deserve 2 : the euphoric feeling experienced upon witnessing another experience the consequences of their arrogance.

That an antivax senator , whom called COVID-19 a hoax, died of the disease gave me an unexpected boost of shadendorphins.
