The word Sus is an established shortening of the English words suspicious or suspect. It was first recorded in English in the 1920s, appearing as "sus." in 1920 and as Sus in 1925, both meaning "suspicious" or "suspected" (Merriam-Webster). However, other sources date the adjectival use to 1955 (Oxford English Dictionary; Green's Dictionary of Slang) or 1935–40 (Dictionary.com). The noun form, meaning "a suspected person" or "a suspicion," was first recorded in the 1930s.

By the 1990s and early 2000s, it spread to urban communities in the US and UK as general slang for anything questionable. The word experienced a dramatic increase in popularity in 2020 with the rise of the online multiplayer game Among Us, which was released in 2018. It quickly moved beyond gaming circles to become common across social media platforms, particularly TikTok, in 2020.
