SCP-106, also known as 'The Old Man' or 'Radical Larry,' is one of the most iconic entities from the SCP Foundation collaborative fiction project. Characterized by his decomposed appearance and ability to pass through solid matter while leaving a corrosive trail, the character became a meme staple within the SCP community. In the meme world, SCP-106 is often used to represent someone unexpectedly emerging from a dark place, being extremely 'corrosive' or toxic, or to parody the terrifying 'Femur Breaker' sound associated with his containment. His ability to drag people into a 'pocket dimension' serves as a perfect metaphor for being ignored, canceled, or simply disappearing from a social situation.
