Knock out is an idiom with multiple meanings and uses. It is often used to describe rendering someone unconscious through a powerful punch or blow. This usage, derived from the sport of boxing, is a common goal when facing opponents in the ring.

The origin of the term knock out can be traced back to the late 19th century.
