An own goal, also called a self goal, is where a player performs actions that result in them or their team scoring a goal on themselves, often resulting in a point for the opposing team, such as when a football player kicks a ball into their own net or goal, awarding the other team a point.
The term has become a metaphor for any action that backfires on the person or group undertaking it, sometimes even carrying a sense of "poetic justice".
