Top Definition
A fear reaction that comes from terror rather than surprise. Typically defines an increased body temperature and slight shaking of the hands, but none of the typical symptoms of fear (such as an increased heart rate or breathing faster.) Named for Junji Ito's Uzumaki manga, which is probably one of the most well-known things to cause this reaction.
He spent the hour or so after reading a bunch of horror mangas sitting in the corner, complaining about an Uzumaki reaction.
