Originating from the 2018 online multiplayer game Among Us, the term 'Sus' is a shorthand for 'suspicious.' It became a global cultural phenomenon in 2020 as players used it to identify potential imposters during emergency meetings. The meme typically features the 'Red Crewmate' or the distorted 'Jerma985' face, representing the paranoia and accusation inherent in the game. It has since transcended its gaming roots to describe any situation, person, or object that feels untrustworthy or out of place in everyday life.
