There are subjectives, and then there are these. While you may believe a work fits here, and you might be right, people tend to have rather vocal, differing opinions about this subject. Please keep these off of the work's page.
This author's work is a prime source of narm of varying degrees, along with defying science at every opportunity and using a few offensive scenarios. However, this extremely long story takes the cake in just the second paragraph.
Cori Falls's attempts to portray genuine angst and drama often fall under this, particularly "The Power That's Inside" and "A Warm Place".
Shy Snootles writes the most Wangst-ridden, over-the-top, Tastes Like DiabetesSkywalker dramas imaginable. "A New Life Part 1," "A New Life Part 2," and "The Hardest Test" are post-ROTJ AU's that consist entirely of hysterical blubbering and sobbing over Anakin's Dark and Troubled Past as Darth Vader and all sorts of wailing and crying over pain and forgiveness. The sheer melodrama is nothing short of awe-inspiring, and that's before you get to the equally hilarious reviewers who thought these were the most intense, gut-wrenching fics they'd ever read. It's also comprised of many, many overwrought Walls Of Text which just beg for a Dramatic Reading.
The truly sad part is that, unlike the other authors listed here, Shy Snootles would actually be a pretty decent writer if she only learned to tone that crap down.
Any time someone tries to get clever while writing a sex scene. Admit it, hearing one's member described as a "throbbing giggle stick" or reading someone yell out "Here cums the mine digger!" has a tendency to elicit more laughter than arousal.
From Alvan An The Chipmunks 3 The Second Squeakuel: "Brittany was screamin an experiencin pain like she'd never felt before, an Ian was laughin with pleasure an sadism as he made the tiny female chipmunk scream in agony an bleed very bad the bathroom floor was covered in a mix of blood an semen from Ians cock." Most of Alvin an the Chipmunks 3 is pretty narmy, but this sentence takes the cake.
The main character yells "NOOO! WHOEVER DID THIS WILL PAY DEARLY, BECAUSE I LOVED THEM?" after finding the little girl who took him in and her father dead along with the rest of their village in the second chapter.
"Soil, is my power." Supposedly, it was taken from the Final Fantasy: Unlimited anime along with the Magun, but that doesn't make it much better.
"I will rip out your hearts eat them then crap out your souls, you will taste oblivion, which tastes like Red Bull, which is disgusting!" Vash's attempt at a Badass Boast after combining his Super Saiyan and dragonforms in early Part 6.
What makes the above quote even worse is that it's ripped from an episode of Red vs. Blue.
"Deserving": "I hate that you have a cock. I hate it! I hate that I am married to someone who has a cock!"
Richard crying "Pah pah, up pah pah, up" when the Diabolus Ex Machina has left Snape chained to the floor becomes funny rather than heartrending for three reasons: Firstly, he's completely unharmed. Secondly, it's hard not to hear it as the "oompa-oompa-oompa-pa" trombone from The Music Man. Thirdly, it's more than a bit reminiscent of the "Profesor McGoogle did a spell so that we were all chained up" scene in My Immortal.
"LUBE! Always lube. Don't make me repeat it," came the menacing voice.
Harry asking "What happen?" in the middle of a theoretically dramatic scene is impossible to take seriously.
Fanfic-as-traced-comic How I Became Yours is awash with Narm; in fact, one could say that every page is visual Narm just because of the terrible art, but the dialog and Walls Of Text take it Up to Eleven. The most famous would have to be "chard monster," but Aang, Zuko, and Sokka (who are adults here) going "yea lets get wasted!" comes a close second.
There's also the part where Sokka screams "NAAOOOOOOOO!" when being held in an awkward way by Sho after Mai hits Azula in the chest with a knife.
Later in the same chapter, the following is very apt to make readers think of the many times characters are revealed in that way in My Immortal, but especially Dumbledore's appearance ("WHAT THE HELL ARE YOU DOING YOU MOTHERFUKERS!") at the end of Chapter 4:
They were nearly at the doors of the great hall when all their carefully laid plans went tits up, neither Harry nor Hermione could believe who had caused it, Hannah Abbot!
Sirius decides that he needs to re-enter the dating game after seeing how happy Lupin is with Sprout. Unfortunately, his internal monologue phrases it like this:
Sirius was just going to have to do a Moony, he needed to get up off his arse and go for it.
Though it's clear from context what "Dumbledore played the werewolf card" means, it still looks like he took a break from his evil scheming for a quick game of Magic: The Gathering.
And when Watari sees that Dark has shot Mello, in a supposedly climactic scene, Watari just exclaims stereotypically British expressions, yelling "I say, what's all this noise!" and "Bloody bugger! You shot Mello!" A few scenes later, Soichiro twists his mustache "like an evil guy".
A PPC agent once said that a good rule of thumb is "Any fic which has the word 'rape' in its title is probably going to be brain-meltingly bad." She based this evidence on experience with two So Bad, It's GoodLemon fanfics, entitled Shadow Rapes Matthias and Lullabies, Anal Rape and Dental Hygiene. The former was Exactly What It Says on the Tin, whereas the latter had a distinct lack of lullabies or dental hygiene. It also proved that, while it may be perfectly reasonable to think the phrase "Holy fucking shit, he's going to rape me!" when being attacked, it's very hard to take seriously in text, particularly when the character who says it apparently has No Indoor Voice.
"Leif walked into the alley SO ARNOLD HE YELLLED TAKING ADVANTAGE OF MORE POOR YOUNG GIRLS EH I GUESS I WAS TOO LATE TO STOP YOU FROM TAKING THIS YOUNG GIRLS INNOCENCE BUT IT IS NOT TO LATE FOR ME TO KILL YOU."
Where to start with The Girl Who Lived? You could simply say "everything the author inserted into the canon stories", but the real special mention must go to every single one of RosePotter's melodramatic, absurd speeches about whatever takes her fancy at that moment, which happen with alarming frequency (and are often accompanied by her floating in the air with her eyes glowing and winds blowing around her, as though it were not "dramatic" enough). Any speech that features an eleven year old girl reacting to a person she just met making mildly derogatory remarks by saying "You impugn the honor of my parents Malfoy, and those of my friend! Leave!", qualifies as Narm.
According to that work's page, the author actually copied down the entire series word-for-word. That's... wow.
Most of The Last War. The writing is serviceable if overwrought, but it doesn't take long for the plot to cross the line from tragedy into farce. Then there's the bit where Hermione's love for Harry is described as being "like golden water", the bit where they dance to "Always" by Erasure (aka the theme from Robot Unicorn Attack) and the bit where The A-Team shows up for no apparent reason.
Throughout the Team Fortress 2 fic Respawn of the Dead, the Soldier goes steadily insane as he dodges Medic's attempts to give him medication for his schizophrenia. As a result of this, his shovel ends up talking to him and making his behavior more and more paranoid. This actually manages to be quite creepy... before it quickly barrels into the ridiculous, as the shovel starts to hit on Soldier, and he eventually has sex with it. While it's obvious that this was intended to be disgusting and disturbing, the whole situation is so mind-bendingly silly that it's hard to take it seriously. Trying not to think too hard about how it would be physically possible (which is a funny thought in and of itself), let's put it bluntly - try and say "He fucked a shovel" while still keeping a straight face. Made even funnier by Soldier asking the shovel if it was a boy shovel or a girl shovel, just so he could avoid being gay. With a shovel.
Spraypaint was now coming out of Jims body, and he had a bad status. He got heavier and his body flopped down. He was running out of power, Jim: Thank you for this short nice life master, creator, Prof., Fitz—— POWER DOWN. Now Fitz went to go plug him on charge.
ThisLemon fic. It's actually decently written, but the lack of spaces between the words makes it unintentionally amusing.
Homestuck High: a lot of it, particularly John getting visions and developing superpowers because of a blast of dark magic from a burger, the ridiculous Battle of the Bands scene, and the description of the demon's lair:
Sollux hath taken her away from her friendships and had carved her into a crimsen spicked room with mutalated woman hanging from the cielings by their ovulation systems and with the baba fetuses in there eye sockets.
