Trying to make a reason kick command, help?

I've been trying recently to create a Command that'll kick the player from the server, displaying a custom kick message, such as;

**(Player says: kick AvidMalignus being a nub)

(What to be displayed:) You've been kicked from the server. Reason: being a nub**

But I don't know how to do this, help?

Well, you are requesting a script which is not allowed. So I cannot help you
