Reddit/YMMV


 * Acceptable Targets: Fundamentalists (not uncommonly extended to theists in general), police officers, Republicans (except for Ron Paul), any politician who's not Ron Paul or Dennis Kucinich, and Israel.
 * Discredited Meme: Reddit tends to turn memes into these.
 * Eternal September: Reddit longtimers think the site's been in one since it was flooded with Digg refugees.
 * Fandom Rivalry: With 4chan.
 * Fan Dumb/Hate Dumb: Any political, religious or atheist section on the site.
 * It's Popular, Now It Sucks: The site has generally gotten a lot of flak since its sudden rise in popularity when Digg changed its layout.
 * Memetic Mutation:
 * GRANDMA TAKING A SHIT IN THE DARK: From a rage comic where the protagonist goes to the bathroom at night, only to discover his grandmother already using it without the lights on.
 * It went okay.: From a post where the poster claimed that his female roommate would masturbate daily and that he planned to walk in on her. When he finally did, "it went okay."
 * Rage comics tend to agree that the best solution to finding a spider in your house is to not be shy with the gasoline and burn your house down.
 * "No, that's [blank]. You're talking about [phrase].": These are long-running threads about a poster mistaking something for something that sounds similar (the [blank]). The [phrase] will be a description of something else that sounds similar, which the next poster will similarly debunk. Example.
 * SO BRAVE
 * Political Correctness Gone Mad: What some redditors think about r/shitredditsays.
 * The Scrappy:
 * r/atheism. In part due to Flanderization, in part due to real anti-theistic or more often than not smug sentiments by many of its posters.
 * This is the same reason that r/politics is a close second. More proof that you should never discuss politics or religion in polite company.
 * r/mensrights is widely reviled across the internet for being a hub of misogyny.
 * r/jailbait, and any related subreddits. This got worse when Something Awful investigated, and found the following details:
 * violentacrez, the person who created these subreddits and a known pedophile/child porn distributor, was friends with many of the higher ups.
 * The mods knew full well that these subreddits were distributing child porn, but did nothing about it because it was against free speech.
 * The threads complaining about these subreddits were swiftly removed.
 * The servers were run by Amazon, which specifically stated in their rules that it was against the rules to post offensive content.
 * Eventually, the subreddits were deleted and it was made a rule not to post CP, but the fact that they had to be pressured into doing it rather than deleting it on the horrible content alone is questionable at best, and despicable at worst.
 * r/shitredditsays, for the community's supposed combination of Hair-Trigger Temper and Political Correctness Gone Mad.
 * "Stop Having Fun!" Guys: The people who complain about reposts.
 * They Changed It, Now It Sucks: A certain Image Board hates what Reddit has done to rage comics.
