c!

c! Is used most commonly by Dream SMP fans (mostly on twitter) to define someone on the Dream SMP's Character.

C! Is just an abbreviation of canon/canonical.

When using c! one is referring to a character rather than the person portraying said character.

c!Ranboo is very forgetful.
While Ranboo is probably not as forgetful as his canonical self.

/c/ 

Anime/cute section of 4chan. Calm and sporting a slow post rate, /c/ is a novelty compared to the other boards. Mainly an imageboard meant for posting images of anime/videogame girls that are cute/moe in nature.

"Wow, /c/ is on its way to its one millionth post! Sure took it long enough..."

"Gee, Bill! How'd you get so many pictures of Konata Izumi?"
"I found them on /c/."
