Vogon Poetry is poetry written by Vogons, a fictional race in Douglas Adams' The Hitchhiker's Guide to the Galaxy. According to The Guide:

Vogon poetry is of course, the third wors in the universe....The very wors poetry of all perished along with its creator, Paul Neil Milne Johnstone of Redbridge, in the destruction of the planet Earth....Listening to it is an experience similar to torture as demonstrated when Arthur Dent and Ford Prefect are forced to listen to the Vogon captain's poetry prior to being thrown out of an airlock--Wikipedia
