Top definition
A term for any illness or sickness that quickly spreads throughout a work environment. Usually a bronchial infection, it is normally caused by a virus or highly resistant infectious bacteria. Normally Joann Lung is very difficult to recover from, resulting in the loss of work and vital PTO. Joann Lung, also known as "Joann's Plague", "The J Plague", or simply "J Lung" may be anything from the common cold to aids. When exposed, one should always assume that at the very least they have contracted SARS, or XAR Tuberculosis. The original "Joann Lung" was a highly infectious and resistant bronchial infection, which spread through several Utah medical labs, hospitals and local businesses. The original carrier, being a modern day "Typhoid Mary", went by the name of Joann. Hence the term Joann Lung, later shortened to The J Plague by local residents.
Example 1: Office Worker 1: Dude, did you hear Johnny hacking it up earlier? I just know I'm gonna get Joann Lung.
Office Worker 2: Wrod, it's probably the SARS.
OW1: Wrod. We're Fuct.
OW2: No doubt.
