I think you were referencing the irl chalk apocalypse, where mathmathians were hoarding a special brand of chalks. Whatever tf were you going to do with that is beyond me.
A comedic plot point where the favorite airhead innocent FMC were asked to advertise a product, a comfy chair, which she passed out sleeping on live stream, making her famous and that comfy chair company STONKS
1) not using tiktok
2) never heard chalk thing
3) Conversation was confusing (there are like skips / holes in the dialogue)
4) What are you asking ????
Mathmathicians heard the Rolls-Royce of chalk was being discontinued so they went into a panic with the prospect of not being able to use this special chalk anymore. This happened back in 2015 iirc.
