These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Broken Base: There used to be a significant amount of mutual hate between SS 13 servers and server populations. Nowadays, though, the servers tend to be relatively friendly toward each other, with significant crossover between Goonstation, /tg/station, Baystation, and the other servers' playerbases.
Crazy Awesome: Most players either are this or aspire to be. Sometimes admins have let usually bannable offenses on the game slide if they're spectacularly crazy/entertaining enough.
Butt-bots. Completely useless to anyone and yet so stupidly hilarious that you're bound to see quite few every couple of games.
Goddamned Bats: Anywhere that isn't the Station area tends to be crawling with all sorts of violent creatures/robots. Thankfully most of them go down quickly if you're well-armed (which you should be before you even think about exploring).
Growing the Beard: Around the time it got new, superior sprites and a far better backstory created by the Goonstation devs. It seems to be growing a second beard now that the various communities have banded together rather than fighting with one another.
Love It or Hate It: Because of its steep learning curve. It also takes a certain mindset to enjoy it, as your character can be killed very quickly.
The clown job. People who play the clown a lot love the job while pretty much every other player hates it with a passion (for why, see The Scrappy entry below). Servers frequently suffer problems with crewmembers trying to maim the clown at first sight.
Love to Hate: Clowns. Despite being completely and utterly loathed by pretty much everyone except actual clown players, they're frequently featured in art and descriptions of the game, bordering on being the game's unofficial mascot.
Mary Tzu: Goonstation had the T.U.R.D.S., which started as a project to make an exclusive elite security team controlled by a whitelist of usernames hand-picked by the admins. Their actual implementation turned out to be an unstoppable army of baboon-faced heavily-armored mooks with obnoxiousCounter-Strike guns and an implant lock system that was imposed on almost every interactive object in the game. The average number of successful traitors rapidly shot down to 0.
This has all recently been replaced with the revamped Head of Security job, a whitelisted Security Officer with access to everything and an arsenal to boot.
Memetic Badass: plenty of notorious players. Special mention must be made of Cuban Pete, a former player of /tg/station, who was capable of building bombs powerful enough to crash the server. His shenanigans eventually resulted in /tg/station implementing a hard-coded cap on explosive power, simply from how destructive a single player was capable of being. Pete is now immortalized in arcade names, alcohol brands, and more.
Paranoia Fuel: Players tend to be incredibly paranoid, suspecting everyone of being a traitor, griefer, or just an idiot who thinks the game is meant to be played as arena deathmatch. Cue violence.
Try standing right next to someone for an extended length of time and see if you don't get beaten up. Personal space is in full force here.
Some extremely paranoid players will immediately suicide/space their own character if they suspect a round will get derailed by the "admin bus".
It gets worse considering that many servers have explicit restrictions on what each player is supposed to know about antagonists, depending on their job. So if you are a lowly assistant, and see someone wearing some spanking-new No-Slip Syndicate Shoes™, furiously typing in their PDA, with a Syndicate Balloon™ on the other hand, as everyone else's PDAs are unexplicably exploding left and right, you can't just act upon it, lest you get banned for metagaming.
The Scrappy: The assistant job, in general. This is mostly because, due to the fact that assistants have no set duties, they mostly wander around the station and mess around with people who are trying to actually do their jobs.
The clown due to some players thinking it's basically a license to do whatever they wish and get away with it. The Mime from /tg/station even moreso depending on the player, as they have the perfect excuse to stay silent the entire round.
A lot of the more overspecialized jobs like lawyer or librarian. Since jobs like this are only useful on certain occasions, crew members in those positions have nothing to do and may just wander about the station getting in everyone else's way.
The security job can be this, due to how prone to abuse it is.
Scrappy Mechanic: When in doubt, blame BYOND. The server software is notorious for lagging beyond playability on occasion. And there is no DC protection of any kind; if the server experiences connection issues your character is a sitting duck for the few players lucky enough to stay connected.
The clown car for being a complete Game Breaker that basically lets clowns murder the whole crew in ten seconds flat. One of the biggest reasons the clown job is hated by all the other players. It's so hated that most servers have just removed it altogether.
The Atmospheric mechanics are a complete mess. Pretty much everyone that gets the Atmospheric Technician job just grabs the fire axe and go off to do something else, simply because the system is so horribly impractical.
Spiritual Licensee: This is probably the closest thing to a Sealab 2021 game that you'll ever get.
Squick: The Goonservers are very good at this, featuring such ways to die as being force-fed poo until the toxic damage kills you, having your butt surgically removed and worn like a hat, or exploding into Ludicrous Gibs from contracting GBS.
/tg/station is very liberal when it comes to cooking. The kitchen comes equipped with a meat grinder for Will-It-Blend experiments, resulting food will be labeled as "Urist McAssistant's Meat Burger", and nobody will bat an eye. You can also order brain burgers, which are exactly that: a human brain in burger bun.
They Changed It, Now It Sucks: Almost always happens on the Goonstation servers, especially if it's a bugfix or nerfing a griefmonger feature like Chemistry.
Also, every suggestion thread on a Goonstation forum will be shot down from someone giving a copy paste answer related to this. This is not to say that some brilliant ideas haven't passed, just that the author had to take far too much time to bullet proof it.
Hilariously, three notorious cases have been banned from the Goonstation forums to avoid this type of reaction.
