It’s basically REEEEE but longer
I was asked to elaborate on something I called ‘Mad Nerd Purple Prose’.
So I will.
You’ve likely seen it before, because from 2005 to roughly 2012, maybe even longer (and it’s still around) Mad Nerd Purple Prose dominated the internet. And yet it’s sort of a hard thing to describe, even with the name I gave it. If you’ve ever read a 'bad webcomic review’ it was probably in Mad Nerd Purple Prose. If you used to follow individual nerd bloggers who wrote about comics or b-movies or sci-fi or whatever, you’ve probably seen it. Hell, TGWTG and all their contributors practically are an entire web brand dedicated to the video form of it (or were in the early 2010s, no comment on their modern incarnations.)
But I guess a more context-free definition would be: when someone employs needlessly flowery language and excessive 'humorous’ or hyperbolic metaphor to attempt to criticize something that really doesn’t deserve the amount of effort being employed. To quote a specific bad webcomic review:
“Am I calling the author the literary equivilent of a pedophile? Yes I am.”
THAT is Mad Nerd Purple Prose.
It’s hard to pinpoint what exactly the root behind it is. It all seems to come together in a big mishmash of horrible. Condescension, smug superiority, combined with the impression the person writing it is gritting their teeth and has their hands balled into little fists, seething. The portrayal of oneself as a super genius through excessive, wordy language and grandious insults or negativity while simultaneously implying scorn towards anyone who disagrees.
That’s the best way I can put it at least. Identifying it is really more art than science.
