Where does pretty sus come from?

Sus, as specifically for short for suspicious, spread online in the 2000s. (Sus as short for suspect is much older, as you can learn in our About This Word section for sus).

The phrase pretty sus went viral video game Among Us. Originally released in 2018, Among Us surged in popularity in September 2020 when gamers livestreamed the game while staying at home during the COVID-19 pandemic. 

In this online multiplayer game, players get assigned as alien impostors among a space crew. The impostors’ goal is to kill the rest of the crew without being caught and then voted to be executed. Through deception, the impostors try to cast suspicion (sus) on others to avoid being killed themselves.

So, why did pretty sus go viral because of this game? Ridiculously murderous imposters fooling delightfully bean-shaped crew members all by simply accusing someone else of being pretty sus—with neither logic or evidence.

As the Among Us player base would say, that sounds "pretty sus." However, there is a perfectly rational explanation why Among Us 2 was canceled.
