The Femur Breaker meme originates from the survival horror game 'SCP - Containment Breach,' based on the collaborative fiction project, the SCP Foundation. In the game, players must activate a hydraulic press to crush the leg of a D-Class personnel—a process known as the 'Femur Breaker'—to lure the dangerous entity SCP-106 back into containment using its attraction to human suffering. The meme gained notoriety primarily through the haunting and visceral scream audio associated with the procedure. It is now widely used in internet culture to represent extreme physical or emotional pain, often paired with unrelated videos or images where a character is about to experience a loud or painful disaster.
