I'm gonna be using lots of names of people that no one here knows about, because if I kept saying "a friend," "another friend," "yet another friend," etc. it would get annoying.
Online Friends
1)

- This is the Skype guy that appears when you type (dance). Usually repeated several times over several rows and often earning the comment "sexy." Began when my online family, The Chaos Chambers, had its own short-lived streamcast radio and we operators were DJing. It didn't work thanks to really stupid lag issues, so Ryo (who was running it) started a chat with a 10x20 block of the Skype guy dancing. It was great.
2) Dribbling - Knight dribbles. Ryo double dribbles. Yul triple dribbles. And Jerec? He quadribbles. I wasn't even around when this started. Ryo and Knight were speaking with Rei about her boyfriend, and they began mocking him. She said he played basketball, and Knight said, "He double dribbles." Somehow it got twisted into "Ryo double dribbles." It reached its peak during those few Skype sessions, when Ryo would kick Knight and Jerec from the conversation when anyone (usually me

) mentioned it... and it of course was mentioned several times.
3) Grapes - Said to be the secret to the power Jerec wields. It isn't. One day, Jerec couldn't remember the password to his old email account. Mizu said, "Try grapes," but offered no explanation. Later, Jerec was still having trouble, and Mizu persisted: "Try grapes." But this time he added "...not that grapes is my password." Grapes was not the password to either Jerec or Mizu's email accounts, but after that any password was referred to as "grapes." It was even used by some members of the CC for throwaway accounts.
4) -_- and "ur face" - An emoticon and expression used by former-user Huy. Huy can be summed up in the word "moron." He was very smart and yet still a perfect moron. -_- was the only emoticon he ever used, and "ur face" was a retort he often used. He's banned now (we got fed up with him

), but he remains in the CC by our uses of the face and expression. And it is always "ur," never "your."
5) Commies - Used to refer to those unvoiced in the IRC chan. In the CC we have several members who prefer to go voiceless and sit at the bottom of the list, along with the bots. We jokingly refer to them as "commies" (never "communists") because of the way they are equal in the nick list with the bots, which are supposed to be "below" real users.
6) Knights of Ownerage - Official definition: "The term does not exist and has no meaning. You are reading nonsense. Go away." Jerec created this organisation on a whim one day, but declared it covert. Since we then knew of its existence, he insisted it did
not exist. The acronym version (KoO) often pops up randomly to perplex who do not know of this organisation. And they shouldn't know about it, considering it doesn't exist.
7) Weasel Paste - The most versatile substance in the universe, exclusively sold by CC Brand. Made from 100% weasel plus 20% wombat based filler. I've no clue how this started, but you can do
anything with weasel paste.
8) Poodoo - Coined by Yul. I don't really want to know what it is.
9) The Grammar Hammer - I wield the Grammar Hammer, sister of Thor's legendary Mjolnir, and use it to punish those who offend the Grammar Nazis. Oftentimes it ends up being used against me, as I tend to point out my own mistakes which others don't notice.
Offline Friends
1) Pregnancy by hand-holding - Began in 6th grade. During Band, Emily, Katie, and I would often pass a piece of paper between each other and write really stupid stories. I drew a picture of Eiko and Vivi from Final Fantasy IX holding hands one day, and we began a story about them when they were older. Eiko was suddenly pregnant, and Vivi shouted, "But all we did was hold hands!" to which Dagger cooly replied, "That'll do it."
2) Pescado - Cameron took Spanish, and he and another Spanish student were conversing in Spanish one day after school as I idly walked beside them. So at a pause, I interjected, "Pescado," knowing full well it meant fish. Cameron cracked up, while the other student was just confused. Pescado has evolved from a mention in Spanish to a full entity that lives with Cameron. Pescado has a dorsal fin that spins to reveal the hidden, razon-edged doisal fin, his head spins, his cheeks blinks (inspired by a Finding Nemo toy), he bleeds, and he sings the Hamster Dance song backwards.
3) Speaking backwards - Cameron and Emily were goofing around on the phone, and Cameron recorded part of their conversation. He tweaked it a bit, and reversed it. Certain parts of it stood out, and we utter these as though they mean something during everyday conversations.
There are probably more from both categories, but I've already listed enough.

Freakin' huge post...
