It means "secret or illegal cooperation or conspiracy, especially in order to cheat or deceive others."
The Boston Globe, publicly in the past week, suggested to other papers that they all ought to write editorials on the same day. Some papers said yes. Some said no. All wrote their own editorial.
It wasn't secret. It wasn't illegal. It wasn't a conspiracy. It wasn't to cheat. It wasn't to deceive.
You need to educate yourself before you try to use big words.
