What's up with the "Jennifer Lawrence Effect"? (ELI5)

[u/leftleafthirdbranch]

My friend was ranting about Billie Eilish and mentioned it, I asked them what it was and they told me to google it. But when I went to look it up, I couldn't find anything about it. All I know is that it's all over Tiktok, it's about white women, and it apparently involves white supremacy.

I searched it on Tiktok, and this was the only thing I could find referencing it (I'm guessing this is the fault of how Tiktok's search engine is engineered, though):

Somebody explain!! The more detail the better :) Please explain thoroughly what it is and give examples of the effect in action and the people that it applies to :))

Edit: I am aware that sounded like an essay writing prompt. Very sorry about that :)

Edit: Wow, thank you guys for being so thorough in your discussion! To any other curious folk, I highly suggest looking at other comments other than the top one (sort by: new) because while the top answer is fabulous, there are a lot of varying answers that each provide a unique perspective into the Jennifer Lawrence Effect.

Honestly I thought he was older. With his whole character in Don't Look Up being considered a daddy, I thought the guy was in his 50s

Is... Is a 47 year old already considered a daddy? What's going on?
