A bad attempt at trolling in which said troll masks said insults as a "critique" of their victims work.
Often the person rants on about little details that the author could have easily fixed on their own and going on about how the characters in said author's story is a Mary Sue even when they have little to no Mary Sue traits at all.
And on occassion rarely fixes their own grammar, never uses capital letters or any form of punctuation mark whatsover.
Also claims that the victim is the one that needs to use a dictionary when he/she is the one that needs it more than the victim.
"Did you read the last Failtique from mr failtroll wannabe over there?"
"Yeah, major fail overload."
