What does kafka-esque mean?

Franz Kafka was a unique writer. His style, subject matter and enlightening viewpoints have led many to acclaim him as Europe's most influental writer.

One his most famous works is The Trial. (Highly recommended, full of poignant observations, and, in its weird way, highlighting the predicament of 'man versus authority', plus the bonus of a thought-provoking surprise ending!)

In the light of 'the world as seen by Kafka' other works or surreal situations have been described as 'Kafkaesque'. i.e. like something in Kafka's writings.
