Pornographic poetry. It is often used by people that want to look semi-intelligent. They use it to profess their undying love in a poetic sense. The worse kind uses forced rhymes and dumb synonyms.
An good example of bad pornoetry:
"The oyster of lust
opens to the world
As thousands thrust
their spears unfurled
Firmly into her socket"
"The oyster of lust
opens to the world
As thousands thrust
their spears unfurled
Firmly into her socket"
