Vogon Poetry is poetry by Vogons, who are a fictional alien race from the planet Vogsphere in the Hitchhiker's Guide to the Galaxy. It is REALLY BAD poetry. "Vogon poetry is of course the third worst in the Universe."
The very worst poetry of all perished along with its creator, Paula Nancy Millstone Jennings of Greenbridge, Essex, England in the destruction of the planet Earth.
Oh freddled gruntbuggly,
Thy micturations are to me
As plurdled gabbleblotchits on a lurgid bee.
Groop, I implore thee, my foonting turlingdromes,
And hooptiously drangle me with crinkly bindlewurdles,
Or I will rend thee in the gobberwarts
With my blurglecruncheon, see if I don't!
