A serious affliction that may initially resemble Severe Accute Respiratory Syndrome (SARS) due to the copious amounts of phlegm, coughing, and unsightly/ungroomed appearance. This condition, which applies to specific individuals (aka "Jacks"), is not known to be airborne-contagious, but there is insufficient evidence to determine if it can be contracted through bodily fluids or prolonged exposure in unventilated areas. There is no known cure.
Person A: "What is wrong with Jack, I hope that isn't SARS?"

Person B: "No, it's not SARS. It is JARS"

Person A: "Oh, that's good."

Person B: "No. Actually, it is terrible."
