<unk> , from Southeast Asia, is a condition in which abnormal behaviors result from a person experiencing a sudden shock. When surprised, the affected person typically engages in such behaviors as screaming, cursing, dance movements, and uncontrollable laughter, and will typically mimic the words or actions of those around them. Physical symptoms include an increased heart rate and profuse sweating, but no clear physiological source has been identified.<unk>  is considered a culture-specific startle disorder that was historically regarded as personal difference rather than an illness. Similar conditions have been recorded within other cultures and locations. For example, there are the so-called Jumping Frenchmen of Maine, imu among women of the Ainu people of Japan, mali-mali or silok among Filipinos, and bat-schi () among Thais; however, the connection among these syndromes is controversial.
