Spontaneous green day disorder (SGDD) is a very common disorder in which one will spontaneously start singing or humming a green day song. This condition can only be treated by converting the affected into a blink-182 or nirvana fan. This condition is found most commonly among people who grew up during the final years of the tv show "Seinfeld".
