if you're talking to your special someone and all they say is "ok" change it up and say "ko" means the exact same.

gilinsky: hey I saw one of the girls from school at the store today.
maggie: ok.
gilinsky: she smiled at me.
maggie: ok.
gilinsky: is "ok" all you're going to say?
maggie: ko

OK backwards. Originally from Short Circuit 2 (1988), K.O. Derf is OK Fred backwards. Became more common with the rise of chatrooms and IM with people who can't or don't waste time trying to type well.

fred: are you ok?
#5: Functioning 100%. Perfectly K.O., Derf!
fred: it's fred
#5: That's what i said, Derf!
