Sus or "sussy" is a slang word that comes from "suspicious" or "suspect" . It became popular with the video game "Among us" or "amogus" as some people call it, and is used when wanting to point out one individual's suspicious behaviour , wether that is acting like an "Impostor" in the game "Among us" , or doing something in real life that seems off and strange (the meaning can derive in real life)
Andrew: Hey Dave , did you see how Jake held my hand there , and he was like he's about to kiss me!

Blue: Guys, I called emergency meeting 'cause I think Red is an Impostor. I have been secretly following but have not seen him commit any task whatsoever , in addition, he was right beside the body we found on electrical.
Red: Blue sus
Game: Blue was not The Impostor. 1 Impostor remains.
