Although commonly used in a colloquial and less-violent sense, the phrase is particularly associated with a specific sociopathic culture-bound syndrome in the cultures of Malaysia, Indonesia and Brunei. In a typical case of "running amok", an individual (often male), having shown no previous sign of anger or any inclination to violence, will acquire a weapon (traditionally a sword or dagger, but currently any of a variety of weapons) and in a sudden frenzy, will attempt to kill or seriously injure anyone he encounters and himself. Amok typically takes place in a well populated or crowded area. Amok episodes of this kind normally end with the attacker being killed by bystanders or committing suicide, eliciting theories that amok may be a form of intentional suicide in cultures where suicide is heavily stigmatized. Those who do not commit suicide and are not killed typically lose consciousness, and upon regaining consciousness, claim amnesia.
