What Does SUS Mean?

SUS means "Suspicious."

SUS is a slang word used widely, both offline and online (especially in the online game Among Us), to mean "suspicious." SUS is typically used to refer to someone or something that seems dishonest, untrustworthy, or fake. For example:
  • Toni: Did you have a look at that camera on Amazon.
  • Jo: Yeah, not sure though. A lot of the reviews are very SUS.
  • Ali: My parents will be away all weekend. We will have the house to ourselves.
  • Jo: It's not like them to trust you like that. Where are they are going? It seems a bit SUS to me.
In the popular online game Among Us (in which players have to find a killer in their midst), SUS is used as an abbreviation of suspicious, to call out players believed to be the killer (or "impostor").
