Giving the impression that something is questionable or dishonest; suspicious. This word gained popularity with being the catchphrase in the online multiplayer game among us.

A shorter version of the word "suspect". Usually used to define someone or something that looks suspicious or untrustworthy.
Bob: Hey let's ask that guy for directions

Larry: Nah, he looks sus as fuck

Suspicious, but more... "lit". Used as a replacement for suspicious such as when a friend is being awfully quiet.
"Ay yo dad"
"Ya, Chad?"
"Brad's being awfully quiet today isnt he"
"Ya he is"
"He's acting pretty sus dad"
