Sussy became popular slang from Among Us, where players shortened suspicious to sus and then sussy during the game's peak around 2020 and 2021. The kawazaki part plays on Kawasaki, the Japanese motorcycle name that is often misspelled in meme titles and paired with loud revving sounds online. Clips mixing a sussy accusation with an unrelated engine noise spread on short video and soundboard sites as a random humour format, and this version is still shared for its abrupt, nonsensical pairing rather than any single original scene.
