“Sus(s)” (among other meanings) is a clipping of suspicious/suspect/suspicion. The OED has plenty of citations. E.g., “It seemed a bit sussy to me” (1965), “What you nick me for? Sus?” (1936), “I sussed that all the dodgy bookshops would soon be skint” (1960), many many others.
Ok, then maybe the renewed popularity of the term came up from Among Us or it was independently spawned there, as well. Interesting to see “sussy” back in 1965. I’m not sure what the 1936 meaning is, because it sounds different, and the 1960 meaning is a different meaning altogether meaning “figured out.”
Actually, found a nice little article here; it does date back to 1930s police slang (but used in a different manner/construction)
I thought you had meant that “sussy baka”, specifically, came from Among Us.
Widespread use of “sus” specifically as short for “suspicious” is new-ish (maybe a decade or so, cites otherwise notwithstanding). It was certainly nothing ever said in my cohort growing nor seen/heard in movies/media of the era (70s/80s).
Yeah, I remember saying stuff more like “that’s a little suspect…” in the 90s, but not “sus” or “sussy.” That said, first time I heard the word, I knew exactly what it meant. “Cringe” is another one that is obviously an old word, but used differently than when I was growing up. We’d never say something is “cringe,” rather something makes us cringe, or is cringe-worthy (or possibly “cringey.”) And “aesthetic” has taken a new life and usage in phrases like “that’s aesthetic,” which is not something I would ever hear or say in the 90s or even 00s.
And “sussy baka,” according to a very shallow dive on the Internet, comes from a TikTokker named Akeam Francis, borrowing the (newly popularized) “sussy” from Among Us with the Japanese word for “fool.”
Per post #29 of this thread, it was selected via an online poll, which explains a lot. I’m disappointed the OED did it this way, as it appears to have resulted in a ‘word of the year’ that only deserves that title among a relatively small section of the online community. They should have made it clear the online poll wasn’t binding (or maybe it wasn’t, and they should have used more discretion - a bit like how that ship did not in fact get named “Boaty McBoatface” - yes I am aware this moniker was used for one of its tenders).
Watch the (old black-and-white) movie whose title gave us the term. It’s the O.G. granddaddy of the behavior, and really underscores the psychological damage it can do.
