dated A red, swollen, bumpy appearance to one's nose, commonly (but mistakenly) ascribed to long-term alcohol abuse. Technically known as a rhinophyma. The old drunk had all the stereotypical traits—a chronic hiccup, a bright rum blossom on his nose, and disheveled clothes that hadn't seen a washing machine in weeks. More than just being unsightly, people think this rhinophyma is a rum blossom, even though I've never touched a drop of liquor in my life!
