Telling another to kill you, as in, "kill me."

Also "km" or "KM", Km is put at the beginning of a text message to tell the receiver to keep the contents of the message private (as stated in the February 2008 Man Council Mandate TM).

Chosen for how easy it is to type on virtually all cellphone keyboards (its the first choice on both T9 and iTap, and K is directly above M on qwerty keypads), Km does not stand for anything although legend states that it may stand for "Keep this Message private".

After a Km message is read, it must be deleted from the receiver's phone -- allowing a Km message to be read by someone not designated for the message is a severe violation of Man Law, as decided by the Man Council Mach II.

Km is traditionally placed in the first line of a message, followed by a few spaces or line breaks so the reader may comprehend the meaning.

Km applies to only one message, and it pertains to the entirety of the message -- partial Km's and Km's for more than one message are not allowed. Km must be declared in each message that is to remain private.
