lung dung

Cigarette smoke byproducts that accumulate in the lungs of smokers.

<doctor> You've got quite a bit of lung dung buildup on both sides. The only advice I have is to quit smoking.
<smoking advocate> No way! That would be infringing on my civil rights.

Dung Lung

To inhale enough shit stench that the fecal fallout replaces the oxygen in your lungs.

Last time I was in a truck stop bathroom I passed out from Dung Lung and had to be life-flighted to Cleveland.
