Hanahaki disease (hon•uh•haw•kee) noun A disease born from one-sided love, causing the victim to vomit and cough up flowers and petals. Hanahaki disease can be cured, if the feelings of love are returned. These petals can also be removed through surgery, but along with the petals, the feelings go too. "Jasmine developed a serious case of hanahaki disease when she fell in love with a straight girl." "Jasmine is always skipping school. One day she'll be caught." "Jasmine is such a weirdo, what's her deal?"
