coughing up a lung

so i checked, and i do not believe it is actually possible to cough up a lung. but then, there is the real possibility i could be the victim of a new condition: lungus coughedupadolphilus.
i know, i know, i am exagerating this being sick thing a little, but since i don't do this often and don't have things like allergies, i will be the first to admit that i have zero coping skills.
apologies to everyone in the library who has to hear me go through lungus coughedupadolphilus.
