Mkay is a non-standard spelling of Okay, representing an informal pronunciation, typically used at the end of a statement to invite agreement, approval, or confirmation. It's made popular by Mr. Mackey on the Comedy Central animated 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？
