Among Us was released by Innersloth in 2018 and exploded in popularity in 2020, when words like sus and venting entered everyday gaming slang. As clips moved to TikTok and YouTube, sus evolved into sussy, and pairing it with baka, a Japanese word for fool, created the insult joke sussy baka. Short voice clips repeating the full Among Us phrase spread as reaction sounds, edits and soundboard staples. It remains used because the reference is instantly recognisable, even to viewers who no longer play the game regularly.
