slang A mass of mucus or phlegm produced from one's lungs, throat, or nasal passage by snorting or coughing. The kids sat on the edge of the overpass, hawking nose-lungers at the cars passing below. I had a horrible chest infection, so I spent the entire weekend coughing up nose-lungers in bed.
n. a mass of nasal mucus. (see also lunger.) Beavis thought the funniest thing in the world was having a nose-lunger dangling from his chin.
