Mine is "Has made himself another personality, Named CHA"
It comes from an anime I've watched a while back. It means I've given myself a new split personality and a name. I'm not different two people by the way. It's just how I view things when having two split personalities. Plus I've never told anyone about this because I sound kinda insane.
I'll explain a bit:
Cha is my true personality who usually takes the role mostly when I'm at home or away from school. The one who can communicate with others easily and always on the lazy side that just wishes to relax and play some games or day dream off to his own anime world featuring himself.
. Always the one that knows whatever sounds stupid or ridiculous when doing something should just do it and deal with it (How ironic. Heh.) The one that comes on 3DS community as always is Cha.
CHA is my split personality that focuses on things such as school, house work or anything else like video game hacks. CHA is more of my quiet side, mostly serious and afraid to communicate with others. CHA dislikes people if he thinks they're annoying, or if they think too highly of themselves or act like they're the sh*t while Cha just tells CHA not to care and just deal with it because it doesn't hurt anyone.
While Cha is more of my cheerful personality, Cha takes the place on getting along with others, and CHA basically stays away does the work. I never notice when I swap places.
My nickname by most people is Chacha so I thought it was a good idea to give myself a new personality named CHA. I did this because I'm always talking to myself at random times even when I don't notice it.
At certain times I use both my personalities together like Communicating and getting along with people (Cha) and working (CHA) at the same time, it makes together "Chacha" which representing both of my two split personalities. I thought it was pretty cool how I thought it this up myself. It's just me though. Heh.
