An increasingly common condition where, on hearing a Michael Jackson song, a person spontaneously bursts into an MJ dance routine. Symptoms can include a rhythmic jerking of the neck muscles, slow nodding of the head, pouting and thrusting of the pelvis. The movements are often accompanied by squeals, whoops and shouts of Shamone! In extreme cases the patient exhibits zombie-like characteristics such as clawing fingers and twitching before grabbing their own knees, turning and stomping forwards. This often occurs in the company of others with the same affliction, when the condition becomes collectively known as Flash Mob.
