sus

"Sus" is a truncated form of "suspicious" or "suspect." It describes a person, object, or situation that seems untrustworthy, dishonest, or potentially dangerous. The mental image is that of a detective narrowing their eyes at someone who is acting just a little too shifty to be innocent. It is highly informal and rose to widespread popularity through internet culture and the game "Among Us." While it can be used to label actual threats, it is most frequently used in playful, hyperbolic contexts to tease friends or express mild skepticism about something that feels slightly "off."
