1 definition by seekingfuckyear

A situation in which a subject (such as a movie, idea, person, etc.) or argument is over-analyzed and deconstructed to the point where it gets ridiculous and nobody else in the room cares anymore. These usually involve large thesaurus-busting SAT list vocabulary, walls of text, straw man arguments, and lots of repetition. "Autistic" posts are frequent on internet message boards, as many people hold huge egos about their so-called intelligence and self-worth.

May also be useful for a person who can't take a joke, needs to lighten up and stop acting so seriously (real autistic people tend to be literal minded).

Can be invoked when someone claims to hate something, but then constantly brings up said thing up in conversation, either to add more (or repeat) reasons of their hatred or to remind others of said hatred.

"Autistic" comes from a way to describe someone with Autism, a curious medical phenomenon that affects the brain's information processing. Autism usually affects social development, communication, and motor skills. Little is known about the cause of this, thus lots of effort is being put forward towards research.
