"These kind of narrative poems are called toasts. They are rhyming stories, often lengthy, which are told mostly amongst men. Violent, scatalogical, obscene, misogynist, they have been used for decades to while away the time in situations of enforced boredom, whether prison, armed services or streetcorner life."
