What does 'sus' mean?

"Sus" is an abbreviated form of "suspicious" or "suspect," according to Merriam-Webster. It is used to call out someone or something with questionable or dishonest motives.

Though usage of "sus" can be traced back to the 1920s, the term became popular in the 2020s thanks to the multiplayer online game "Among Us", Merriam-Webster reports.

In the murder-mystery game, one player is the "imposter," and others try to figure out who they are. Players often use "sus" to describe others who are acting strange and could potentially be the imposter.

Beyond gameplay, "sus" can be used in various scenarios, such as to call out someone for lying or to describe a person's actions as suspicious or out-of-character.
