Mellencramps 

Extreme abdominal pain and discomfort caused by listening to terrible adult contemporary rock music. In most cases, the sufferer may experience sharp gas-pains, diarrhea, bloating, foul smelling flatus, nausea, and dizziness.
In some extreme cases, depression with thoughts of suicide have occurred.

While browsing through the carpet store, I noticed a Billy Joel song playing. I had to leave because I was experiencing a severe case of Mellencramps. I drove to my friend Rick's apartment, and promptly used his toilet to relieve myself.
