Mkay is a non-standard spelling of Okay, representing an informalpronunciation, typically used at the end of a statement to invite agreement,approval, or confirmation. It's made popular by Mr. Mackey on the Comedy Centralanimated sitcom South Park. It can be used in place of OK.
Mkay是Okay(行，好)的不规范拼法，代表一种非正式发音，通常用在句尾来征求同意、认可或进行确认。这一说法因美国喜剧频道播放的动画情景喜剧“南方公园”里的麦基先生流行起来。mKay可以用来代替OK。
Mkay的美式发音为/m:'kei/，除了mkay，mkay、mmkay、mmmkay也有相同的意思，其实读读这个词，你就能体会到说它时随意的感觉。
For example:
Just leave us some flowers by the door and we'll pick them up later,mkay?
在门口给我们留点花，我们之后把花拿走，行吗?
又如：
Come back in a few hours, mkay?
几小时后回来好吗?
有时，这个词还用来表达一种讽刺或居高临下的感觉：
Drugs are bad, mkay?
毒品不好，是吧?
