sus

What does sus mean?

Sus is a raised eyebrow in three letters. It means something seems off: a story with holes in it, a friend who goes quiet at the wrong moment, an email offering a free cruise. Merriam-Webster describes it as a slang word for saying that someone or something should not be trusted.

It works on people, things and situations equally well. A person can be sus, an excuse can be sus, a link can be sus, and a gas station sandwich can definitely be sus. People usually dial it up or down with a qualifier: "a little sus," "kinda sus," "pretty sus," "lowkey sus," "so sus."

The word is short for suspicious or suspect. Unlike a lot of slang, the meaning is exactly what it looks like, which is part of why it caught on with every age group so fast.

Other meanings. In Britain, older people may connect the word with the "sus law," a power that let police stop, search and arrest a "suspected person" under section 4 of the Vagrancy Act 1824. It was used disproportionately against Black people, drew campaigns such as "Scrap Sus," and was repealed in August 1981, months after riots in which anger over its use was seen as one cause. British English also has the verb suss or suss out, meaning to figure something out.

Examples

• Among Us lobby: "blue vented, I literally watched it. blue is sus"
• Group chat: "he said his phone was dead for three days but he posted a story. sus"
• Parent texts teen: "Email says I won a cruise. Sus?" Teen: "extremely sus. delete it"
• Office chat: "the 'urgent invoice' from a random Gmail address feels sus"
• Classroom: "why is Mr. Lee smiling like that before the quiz. sus"
• Watching a game: "that offside call was so sus"
• Roommates: "someone ate my leftovers and you're being real quiet. kinda sus"

Sus usually follows is, seems, looks or acting, or stands alone as a one-word reply. It is one of the few teen words parents adopt without embarrassment, partly because it is so handy for spotting scams.

Where did sus come from?

Sus feels like an internet invention, but its paper trail runs back about a century.

• 1920s: Partridge's dictionary of slang dates sus. as an abbreviation of "suspected" to 1920, and the adjective sus, meaning suspicious, to 1925, according to Merriam-Webster.
• 1930s: Green's Dictionary of Slang records sus as a noun for "a suspected person" and "a suspicion." Dictionary.com dates the first recorded use of sus to 1935 to 1940.
• 1955: Merriam-Webster's first known use of the adjective in its current sense.
• 2012: An episode of the comedy show Loiter Squad, from Tyler, the Creator's Odd Future crew, included a segment explaining the word, and Know Your Meme notes it had turned up in rap lyrics for years.
• 2017: A Refinery29 dating-slang explainer called sus the 2017 version of "shady," as Merriam-Webster points out.
• 2018 to 2020: The game Among Us came out in 2018, then surged during the 2020 pandemic lockdowns. Know Your Meme dates the word's spike in in-game chats to the game's second wave, around August 2020, with "sus" memes spreading across Twitter, Instagram and Reddit that September.
• September 2022: Merriam-Webster added sus to its dictionary.

Sus, sussy and sussy baka

Among Us left a few spin-offs behind. Sussy is just a cuter sus. Sussy baka, which Merriam-Webster explains as sussy plus the Japanese baka ("fool"), became a meme insult that is mostly affectionate. Know Your Meme also files "Amogus," a deliberately mangled spelling of the game's name, under the same family of jokes. All of these are playful and mostly heard from kids and gamers.

Is sus rude?

On its own, no. Sus has no swearing and nothing sexual in its main meaning, and saying "that looks sus" about a phishing email is good advice. It is still an accusation, so calling a person sus can sting if it is not obviously a joke.

There is one use worth a parent's or teacher's attention. Some kids call a boy "sus" for being affectionate with another boy, implying he is secretly gay. It works the same way as "no homo," and in a hallway it can be a form of anti-gay bullying, even when it is dressed up as a joke.

Calling someone sus because of how they look, rather than what they did, is also worth questioning. Britain's old sus law is a reminder of where that kind of suspicion can lead.

How to reply to sus

• A friend says your excuse is sus: "Check my screen time. I was asleep by ten."
• A parent says "That's sus" when you get home late: "Fair. Here's the whole timeline."
• A coworker flags an email as sus: "Good catch. Forward it to IT and don't click anything."

Is sus still used in 2026?

Yes. Sus has outlived the Among Us craze that made it famous and settled into everyday vocabulary, closer to "sketchy" than to a trend word. An Ohio high school teacher's 2025 list of 100 slang terms, covered by the Deseret News, still described it as the go-to label for suspicious behavior.

Its cousins handle different jobs. Cap says a claim is a lie, while sus only says something smells wrong. If someone is acting on autopilot rather than shady, that is an NPC. For more words that came out of games, see the gaming slang guide.
