Mmm K 

Okay but not really. When you can't or don't want to say, "No", "you're wrong", or, "that's what you think!".

Husband says," I thought the truck was filled with gas so I took the car and filled it, forgot you needed it today."

Wife says,"Mmm K."

Mmm kay 

Sarcastic version of okay. Pronounced by drawing out the mmm sound and giving it a sarcastic edge. Best when used in a patronizing manner. Frequently used in the movie, Office Space.

"We're going to have to ask you to come in to work on Saturday... Mmm kay?"

mmmkah 

The best thing to say to replace OK or synonyms of the OK.
Once you begin to use 'MMMKAH!' you will never stop. It is an addicting thing to say because it is pleasing to the mouth.
You will find yourself replacing words in your vocabulary such as:
'ok', 'alright', 'yeah', 'of course,' 'yes', 'absolutely', 'sure', 'agreed', 'for sure', 'no doubt', etc... Mmmka?!
Inspired while playing the best XBOX 360 game for XBOX LIVE. HALO 3.
