C-H-A-T I-S D-A-D

C-H-A-T I-S D-A-D is a phrase with a typo created accidentally by Kingdom Hearts Wiki IRC user LightMouse. Just a couple days after its creation, it already achieved a sort of memetic status on the Kingdom Hearts Wiki's channel along with "THEN WHO WAS FONE".

Origin
In mid-March 2011, Kingdom Hearts Wiki IRC user LightMouse left the channel for the night when stating the obvious: that the channel was dead at the time. However, the user missed a key (or two) and ended up entering the now-famous message, "C-H-A-T I-S D-A-D."

Usage
Whenever "C-H-A-T I-S D-A-D" or "CHAT IS DAD" is exclaimed on a channel that is dead, or has no activity going on (hence dead), a user who did not exclaim the first message will enter "THEN WHO WAS FONE?" or just "THEN WHO WAS FONE".

THEN WHO WAS FONE?
THEN WHO WAS FONE? originates from a "creepypasta" called "THEN WHO WAS PHONE?" that first made its appearance on /x/ on an online forum called 4chan. The "creepypasta" itself goes:

So ur with ur honey and yur making out wen the phone rigns. U anser it n the vioce is “wut r u doing wit my daughter?” U tell ur girl n she say “my dad is ded”. THEN WHO WAS PHONE?

Pretty creepy stuff, huh? Yeah, I bet you'll think twice about doing stuff like this.

Trivia

 * Chat is no one's father.
 * In fact, chat is dead.
 * THEN WHO WAS FONE?
