"Secretz" (note the Z) n. and v. Is a standard word used when posting a status update or tweet with a social networking service under someone else's name, merely just for the sake of it. It is to make it apparent that someone else is using that person's account.
It was started in the east side of Contra Costra County in California. Since then it has expanded throughout a minority group in the region.
