The Anna Nicole Smith Effect

A modern variation of The Jesus Effect, wherein the majority of people dont care about someone or even like the person(and often disliking them) until they die and then they do a 180 by now worshipping the deceased person and speaking highly of them. They will often go on about how good the person was and act like they didnt dislike/hate/not care about the person the day before they were dead.

A more recent variant of this is "The Harambe Effect"

"Harambe deserved a chance, but they killed him in cold blood."
"This is the Anna Nicole Smith Effect all over again, you didnt care about that monkey but now it dies and youre all about apes rights... Hokay."
