Reactionalysis
A portmanteau of "Reaction" and "Analysis" first appearing on youtube reaction videos alluding to analysis style reactions, first used mid 2020.
Youtuber: Heyyy welcome back to my channel, where i'm doing a reactionalysis to your favourite song!
Viewer: Dafuq, I signed up for reactions, not this analysis shit. I am digging it though.
