The phrase comes from sus, the shortened slang for suspicious that spread widely with Among Us during its peak popularity in 2020. Players used it to accuse crewmates of acting like impostors, and sussy became a sillier variant in memes, remixes and voice clips. This version personalises the joke by naming Avi, turning a general gaming accusation into an inside joke that can be reused whenever that person appears suspicious. Its short, repeatable delivery helped it fit the wider meme sound culture of quick reaction clips shared across social video and gaming communities.
