The FanFiction Critic provides examples of the following tropes:
Author Catchphrase: Several reviewed fanfics have these to the point where she makes fun of it, especially "ne'er-do-wells" and "furry friends" in The Disney Seven.
Critic: Stop saying "furry friends"! Because every time you do, I picture this! (Shows picture from Anthrocon)
Be Careful What You Wish For: During "Face the Strange," Shadow the Hedgehog hits on the Mary Sue, prompting the Fanfiction Critic to be repulsed and ask if they can please have something that's not bestiality. Unfortunately, the fic practically Gilligan Cuts into Dumbledore's incredibly out-of-character pedophilia.
In all of her reviews, though you can't really blame her.
Diane, the text reader, acts like this in the review of several of her reviews.
Dead Series: It's starting to appear this way since she hasn't updated in over a year. Confirmed on Twitter.
Drinking Game: She often starts one up when a fic gets particularly bad, usually when she finds something incredibly repetitive or annoying about it (Purple Prose descriptions of a Mary Sue, run-on sentences, etc). She tells her viewers to join her if they want, but warns them not to drive and to have their hospital number on speed dial in case of alcohol poisoning.
Everyone Calls Him Barkeep: "The FanFiction Critic', obviously, mostly due to the fact that it's part of how she introduces herself at the start of every video. Her real name is Linnie, which generally only her online friends and hardcore die-hard fans call her.
Critic: It was a shocking horror film about an evil German scientist who wanted to join three people togther, ass to mouth, for the sheer purpose of- um... hang on a minute, it was 'cause he wanted... because of, um... it was... um... h-he did it for... science? Oh hell, do people even need reasons for doing anything anymore?
Reappears in several subsequent reviews, usually of particularly heinous fanfics. She often makes a Drinking Game out of it when there's something repetitive and annoying, encouraging her viewers to join in but to also have their hospital on speed dial, and not to drive.
The Mary Sue in Forbidden Fruit is so ridiculous that she eventually just comes back from Diane's reading already draining her flask.
The Long List: In one review, she gives a list of warrior goddesses (complete with pictures) to comment on how she always saw nice, fluffy Incorruptible Pure Pureness goddesses in fanfic and actual mythology wasn't like that. Sometimes her explaining what's wrong with a fanfic can go into this territory as well, because most of the stuff she reviews, well, does have a lot of things wrong with it.
Shower of Angst: FanFiction Critic had to keep on taking showers because she was reading a fic involving Bella Swan getting raped by Edward Cullen and Bella was okay with it. Later parodied, as she leaps up for showers repeatedly over the course of a single review. Eventually, she has a toothbrushing of angst after quoting a racist fanfiction, claiming it made her mouth "feel dirty."
The Swear Jar: She uses the Cube of Profanity. She mentions in one episode that once it fills up, all the money will be donated to the Red Cross.
To the Pain: Her descriptions of what she'd like to do with the author of Back to the Frollo get vivid, especially when she dresses up as "The Fanfiction Devil" and begins describing the center of Fanfiction Hell. It's a running trend during the worst of her reviews.
