The term "sus" is a slang abbreviation of "suspicious" or "suspect." It is used to describe someone or something that seems untrustworthy, shady, or dubious. The popular usage of "sus" grew significantly from the multiplayer game Among Us, where players use it to call out those acting suspiciously and potentially being an imposter. Beyond gaming, "sus" has become a common colloquial expression especially among younger people to indicate doubt or mistrust about someone's behavior or a situation. Sometimes, it can also carry sexual or slang connotations in certain contexts, but its primary meaning remains linked to being questionable or suspicious.
Examples:
- "Red is sus AF. He is following me and acting strange."
- "You’re acting pretty sus right now."
- "That’s sus."
This slang is informal and commonly used in casual conversations or social media rather than professional settings.
