The idiom "punch someone's lights out" is a figurative expression commonly used in informal speech. It is used to describe the act of physically striking someone with such force that it causes loss of consciousness or renders them unconscious. The origin of the idiom can be traced back to boxing, where "lights out" refers to knocking out an opponent and causing their lights or consciousness to go out. This phrase is typically used in a threatening or aggressive context, implying the intention to physically harm or incapacitate someone. However, it is also used metaphorically to convey the idea of defeating or overpowering someone in a non-physical sense, such as in a debate or competition.

The related idiom "put someone's lights out" has a similar meaning to "punch someone's lights out." It is used to describe the act of causing someone to lose consciousness or rendering them unconscious through a physical strike. However, "put someone's lights out" implies a more deliberate and intentional action, often with the goal of ending a fight or confrontation. The addition of "put" emphasizes the forcefulness and intention behind the action, suggesting a stronger and more decisive blow.

A similar idiom is "knock someone flat," which is used to describe the act of knocking someone off their feet or causing them to fall to the ground. It implies a sudden and forceful blow that leaves the person physically incapacitated and unable to continue standing or fighting.
