A placebo sickness that people pass on to others. When someone who acts weird is in a room. Some of the other people will start acting like them because of the confinement. When that happens it is a chong fever.

An annual sickness that befalls lovers of craft beer during Russian River Brewing's annual release of Pliny the Younger. Symptoms include uncontrollable thirst, standing in insanely long lines, talking to no end about how amazing Pliny the Younger is and how all other beers are just practice runs during the off season. Younger Fever can be spread through blogs, bragging, and memories of previous Younger.
