Ascended Fanon: Ever since roo525 dubbed Chipmunk Raocow "Chibi-Cow", Raocow himself has sometimes called his chipmunk form that as well.
Beam Me Up, Scotty!: Many things raocow says end up getting misquoted by fans. "NEVER PUT A MESSAGE BOX ON LAYER 3" (a phrase that's complete nonsense when written like that) is one thing he never said, but are constantly repeated by the fandom. The actual quote is "Never put a message box in a level with layer 3". Admittedly, his angry clenched-teeth style of saying the latter made it easy to miss the frequently omitted words, and the quote was used that way in a Stupid Statement Dance Mix by Generic CAW.
In a video, raocow mentioned Rubber Fishy, whose Let's Play he was watching at the time, causing Rubber Fishy's subscriber count to subsequentally raise rapidly.
While she was quite popular in her own right, when Raocow told his viewers that PinkKittyRose was doing a deathless run of ASMT, her subscriber count jumped up.
Creator Backlash: Toward his Parodius and Mega Man X LPs (see Old Shame below). And especially toward his New! Super Mario World 2: Yoshi's Island LP, because of how infuriating the game was and how unpleasant his playing is to watch, to the point of outright anger at its creator. It's the only game he'll never replay.
Missing Episode: The Viddler-hosted episode of his VIP 3 LP titled "Mercy" was lost when Viddler closed his account.
Old Shame: His "Let's Intermission With Mega Man X", posted in 2010, is made up of footage recorded in 2008. He thinks his bizarre commentary in it sounds cheesy and forced...but a lot of his fans really like the videos.
He considers his Parodius let's play to be so bad it's not even in the archives.
He's come out lately saying that he dislikes his old, intensely "monkey cheese" style of commentary and rampant Save Scumming in a lot of his pre and early-YouTube LPs, saying that it cheapens his enjoyment of the game and that he won't go back to it no matter how many people tell him to.
One of Us: He has participated in discussions on this site, and is aware of the rather unusual situations we have set him up in.
Believe it or not, he watches Minecraft videos. Mainly peteyboo's LPs, but he also likes things such as the Beetlejuice rollercoaster video.
Schedule Slip: Pretty relentless aversion, as Raocow has been uploading daily since 2008, with exceptions given only to when he's physically unable to play (sickness, vacations, computer breakdown, etc). Sometimes this leads to him talking while drawing a picture, when personal trouble arises.
In his playthrough of Takkoman, he lets the viewers vote for which stage should be played next. The most popular stage among the viewers doesn't get played until it's the only stage left, because "it's always important to keep people in want".
When someone complains about one of his gaming habits (like obsessively checking his menu in a Yoshi's Island hack,) chances are he'll do it anyway, only he'll specifically mention how he's pissing off that one guy who was complaining about it.
After someone complained in the comments how often raocow says "I'm pretty good at video games", raocow instead started to say variations such as "I'm pretty skilled at interactive entertainment". The day after that comment was posted, in fact, that was his video intro.
A Youtuber by the name of derschlauepeter requested that the intro of this video be "Hello, it is I, thy favourite roodycoo". Raocow decided to start said video with "...the hell is a roodycoo?" instead.
"Yesterday I've learnt that I lost the boss contest for Copy Kitty, so I'm not going to play this game forever anymore. *game shuts down like it does at the end of the previous videos*"
