sus means Suspicious or suspect; describing someone or something that seems untrustworthy or off. It is best read as usa slang associated with USA.
Anything that triggers doubt can be sus: a person acting shifty, a too-good-to-be-true deal, a text from an unknown number, leftovers of uncertain age. "That link looks sus" and "he's been acting sus all week" are typical uses.
Among Us gave the word its defining scene — a group of crewmates voting on who seems suspicious — and for a couple of years afterwards, saying "sus" instantly evoked the game. That association has faded into the background, and the word now functions as ordinary vocabulary for an entire generation, including kids who never played the game.
It is worth knowing that "sus" is occasionally used with an insinuating tone about someone's behaviour or preferences, which can shade into mockery. In most everyday use, though, it is a mild, almost neutral word for "questionable".
"I'm not clicking that link, it looks sus."
"He left the group chat right after the plans changed?"
"The chicken smells kind of sus, I wouldn't risk it."
"Why is the new guy asking everyone for their passwords?"
"That's beyond sus."
Mild, often humorous doubt; rarely aggressive on its own.

"Sus" as a clipping of "suspicious" has existed for decades — British police slang used "sus" as far back as the 1930s, and the UK's controversial stop-and-search "sus law" made the word politically famous in the 1970s. Its modern life is different: the 2020 explosion of the game Among Us, where players accuse each other of being the impostor, made "sus" one of the most recognisable slang words in the world.
Both, and in practice it covers the two meanings at once — a sus person is a suspect, and their behaviour is suspicious.
No — the clipping is decades old, with recorded British police use in the 20th century. Among Us made it globally viral in 2020, which is why it feels like a gaming word.
Not usually. It flags doubt rather than attacking anyone. It only stings when it implies someone is being dishonest about something serious.
Yes — it is one of the most widely understood slang terms of the past decade, recognised well beyond Gen Z.
