Over its course, RMRK has picked up or evolved a few commonly used memes or catchphrases. Some of them might only be recognised or acknowledged by a few members, though this just makes their use all the funnier when you get an educated response.
These are listed in no particular order, and if you are aware of something that is missing, feel free to update this page with it.
Perhaps the most annoying ever, the LOPL reeked of n00bism, reflected by the member attributed with it's creation; TheRotS. It was undoubtedly originally a simple typing error, (P being adjacent to O), and the intended phrase was LOL. But, being the small minded spammers they were, a few people decided it was a stroke of genius and began to spam it everywhere frequently. This carried on to the point that Crankeye eventually set a wordfilter in place that changed LOPL/lopl back to LOL/lol.
Ctrl & Mousewheel
Invented by FuMannChu personally, this is meant to represent crying for reasons other than sorrow, such as victory. Referring to manly crying can, and most likely will, evoke feelings of success, togetherness, and caring for anoter's pain.
Usually followed by a cry of: "YATATEI OYAJIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII!!"
dwarra has become an RMRK meme of sorts, as in almost every poll, he is included as an option. This almost always confuses new members, as they've never heard of dwarra. What is usually more odd is that if dwarra is included in a poll, it is usually voted for.
Originating from IRC, this silly nosensical phrase was basically spammed for a month. It got the channel in trouble also; due to advocates searching for and spamming other channels on the network with it. It was making it's way onto the forums, until Silverline added a wordfilter than replaced "UHN" with a single space. The wordfilter now seems to have gone, though nobody cares anymore.
This is a meme that started from Zypher or someone, but Dr_Swordopolis loved it so much that he made it into a whole board, site and council over it. 7yay also has it's own memes, such as My Knife is Broken, There's a Snake in my Sentry and other stuff only Dr_Sword and EVAProject01 would know.
RMRK is going downhill
Close to the time SexualBubblegumX left for the first time, he began making posts about how RMRK wasn't as good as it used to be, and that it's going downhill. This spurred other members to satirize this by "claiming" RMRK is going downhill every time something stupid happened. Eventually other directions became involved. This meme was so overused it quickly became hated.
This is more prominent in IRC than it was on RMRK. HaloOfTheSun coined it, saying he has a disorder that prevents him from meowing properly. Fellow members Skanker and threeofspades began to moew as well, in support of his condition.
