KO
Stands for a "Kill of Opportunity."
Could be a noun describing the target, or a verb describing how to kill the target.
When both Sadam Hussein and Usama Bin Laden arrive for the exchange, sniper teams 1 and 2 will take both targets out. Consider any other armed associates at the scene a KO.

We can't risk him getting captured. I don't want to go to jail while he goes free just because that child-raping pos cried police brutality. No, if any of us get a clean shot, we KO his ass! Understood?

Ko
1)K.O. as in "knocked Out" can be used in life when someone is unconcious and also appears in fight games when there is a victor and the loser is K.O.

2)the dyslexic way of saying OK.
(I have a dyslexic friend and this is her joke, its not meant to be hurtful or nasty in any way)

KO
"KO" is the equivalent to the meaning & abbreviation of the letters meaning "OK" and was used on "Mork & Mindy", which is a t.v. series that had aired from 1978 to 1982. Mork is one of the main characters in the series, and an alien from the planet Ork. He would commonly reverse the proper order of human words and phrases that he spoke, by mistake
"Owie! Shazbot, shazbot, SHAZBOT! I stubbed my little toe when I tripped over the footstool Mindy, and it hurt!!! You didn't even ask me if I was KO!!!"

(Mindy replies)
"Oh, Mork! I'm sorry- did it hurt? I think you meant to say that I didn't ask you if you were "OK", on Earth we ask if you are OK if you hurt yourself, not "KO"!!!

***Proper credit must be given to the true comic genius of Robin McLaurin Williams (July 21, 1951 – August 11, 2014) R.I.P.
