Last name of author Franz Kafka. Generally used as a noun to describe "that which has qualities similar to Kafka's litterature". But seeing as how that's kinda tautological, try this. Picture yourself in a small, cramped space. Add women with silk skirts and pillows attached to your head. Then add your father, run away and run into your lawyer who's daughter is a nurse whom you make love with on the floor of a court room that has no walls and where everybody is watching you as you writhe in ecstacy. Then comes the weird part. You find out that you're about to be executed for commiting a crime, but there's no tribunal, no judge, no witnesses, you're just to be executed. But the executioners take so long that you just decide to comply with the law and slash your wrists while eating some schnitzel. You finnally pass away and nobody realizes you're dead until 25 years after, at which point nobody cares about you still.
"Dude, Jimmy just pulled a Kafka"
"I don't know Jimmy, but make love to me anyways"
"I can't I must run now!"
