Frostbite

Frostbite: noun. A bite from the American poet Robert Frost, which causes poetism. A person that receives a frostbite will over time (roughly 3 fortnights) turn into an intolerable, self-satisfied maniac obsessed with trees and dark forests, who constantly carries around loose sheafs of paper covered in incomprehensible scribblings. Cures for the effects of frostbite include drinking Emily Dickinson's tears or wearing Lord Byron's underwear (preferably clean).
