Unater

A combination of the words "unnecessary" and "hater", an Unater hates somebody or some people so much, they can criticise them for the simplest actions and even those who dare say anything slightly positive about them.

See TheCinemassacreTruth for instance, a subreddit which has such a distaste for James Rolfe, anyone who sees him as an inspiration is just seen as bootlicking and block anything which is positive towards James Rolfe unless it's about how he was during the 2000s and early 2010s, often through downvotes.

"Dude, Chris just told be to hang myself because I said I like The Angry Video Game Nerd's newest episodes"
"Wow, what a Unater. Fuckin' asshole"

untertainment 

entertainment that fails to entertain

"Steps into Summer" is untertainment at its very finest, and will be warmly welcomed by those who watch TV with a shotgun in their mouth, trying to pluck up the courage.
(as quoted from TV critic Charlie Brooker)
