A backbreaker refers to professional wrestling moves which see a wrestler dropping an opponent so that the opponent's back impacts or is bent backwards against a part of the wrestler's body, usually the knee. The standard version of the move sees the wrestling scoop their opponent horizontally before dropping to one knee, slamming the opponent's back on their other knee.
