When referring to the popular 2018 video game "Among Us", "Suss out" means to identify and vote out the imposter before he manages to kill all crewmates aboard, this task is quite difficult considering that it is easy for one to be falsely accused as the imposter. An example of a conversation would go as follows:
Orange: Bro, red vented in electrical and me and purple both saw it! I say we suss out red before things get out of hand.
Purple: He's right, I saw red vent in electrical too.
Red: Bullshit! It's clear that their are two liars among us!
