I use the term Parky primarily to refer to my symptoms, not to myself (e.g. “I am super Parky today because my meds are off.”)
I do not think that someone in the PD community (patient or caregiver) using the term is offensive because it serves as shorthand, an inside reference, but if a random person on the street referred to me as a “Parky” I would take umbrage.
Eminem has no place using it as a subject in his music. Frankly it pisses me off that he hasn’t been taken to task for so flippantly diminishing the disease as merely shaking; as we all know there is so much more to it. I would like to see him face to face with MJF and see if he had the cajones/audacity to disrespect him in the same room.
