sus.
Suspicious, questionable, or not quite trustworthy. It can be a genuine concern or a playful reaction to odd behavior.
What does sus mean?
Sus is a shortened form of suspicious or suspect. A deal with inconsistent details might look sus; a friend who suddenly knows the answer to a puzzle may be jokingly called sus. The word flags a doubt, not proof that someone has done something wrong.
The game Among Us helped make the expression highly recognizable online, but did not invent every use of it. Outside a game, the same word can be light teasing or a serious warning. In music, sus also abbreviates suspended in chord names, which is unrelated to an accusation.

The right word.
The right moment.
Use it for a quick, informal expression of doubt, ideally with the detail that prompted the doubt. In a game it can simply signal suspicion about a player.
Do not turn a vague feeling into an accusation or use the term to stigmatize someone’s identity. Explain concrete concerns when they matter.

suss out
To suss something out is to work it out or investigate it. Sus usually describes the thing as suspicious.
A little backstory.
The shortening predates Among Us and has older British and other English-language uses. Its game-related prominence is a later stage of circulation, not a first coinage.
