flatline

A monotonous, expressionless person, lacking any enthusiasm or emotion. The term comes from hospital lingo, where a patient is said to flatline when a continuous straight line is displayed on their heart monitor, indicating death.

"...as excited as that flatline can get. I had to remind him twice to keep breathing."

Flatliner

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.

flatline

Commonly observed amongst youth in an intensive educational programme, such as the IB. The word flatline is used to indicate someone whose brain has (almost) ceased to function. Characteristic behaviour amongst individuals flatlining involve laughing at anything in sight, at each other, or at things that when viewed in retrospect, aren't funny in the least. Flatlining is believed to be the brains natural way of relieving stress on the body after having to actually think for an extended period of time.

Flatlining, when used in a broader sense, can be used to describe someone who is behaving abnormally, though the reason for which, must always be related to the stress and induced low blood sugar levels created by a day of intense learning and having to listen to lecturers repeat themselves like a group of chimpanzees mundanely bantering on about the global banana economy.
