Dottie was having a good time, until she got stuck with that flatliner.
2.
someone who is boring, unenergentic, tired, sleepy.
Dont be a flatliner! Here's a beer, c'mon lets get drunk!
3.
A mindless person or someone with no personality; gives blank stares, especially when presented with ideas or facts that should arouse some sort of reaction in a sentient being. Basically brain dead or mentally challenged. It would be improper to use this against someone who has a real diagnosed disability of course. More like, if you meet someone in a professional capacity whose title suggests they are intelligent, but really they just stand around looking dumb.
