If a friend says that is kinda sus when you explain why you were late, they are not complimenting you. Sus is short for suspicious, and it has become one of the most widely used slang words among teens and gamers. This guide explains what sus means, where it came from, how the game Among Us made it famous and how to use it in conversation.
What does sus mean?
Sus means suspicious, shady, questionable or untrustworthy. It can describe a person, an action or a situation that seems a bit off.
| Example | Meaning |
|---|---|
| That guy is acting sus | He is acting suspicious |
| This link looks sus | This link might be a scam |
| Kinda sus | A little suspicious |
| Sus behavior | Questionable behavior |
| You are being sus | You are acting strange or hiding something |
| That deal sounds sus | That offer seems too good to be true |
Sus can also be used as a verb in some places, especially in British slang: to sus something out means to figure it out or investigate it.
Where did sus come from?
Sus is not brand new. It has been used as shorthand for suspicious or suspect for decades, especially in British English. In the UK, so-called sus laws in the 20th century allowed police to stop people on suspicion, and the phrase sus out has long meant to investigate.
In African American English and hip hop culture, sus also developed a meaning related to questionable behavior, sometimes with sexual connotations. That use is more sensitive and context-dependent.
The modern popularity of sus exploded in 2020 thanks to the online game Among Us, in which players try to identify an impostor. Players constantly typed things like red is sus or that is sus during discussions, and the word spread across Twitch, YouTube, TikTok and memes.

How Among Us made sus a global meme
Among Us was released in 2018 but became a worldwide hit in 2020 when streamers began playing it during lockdowns. The game is about trust and deception: crewmates complete tasks while hidden impostors sabotage and eliminate them. During emergency meetings, players type quick accusations, and sus was the perfect short word. Clips of players accusing each other spread across Twitch and YouTube, and memes such as red is sus and the sussy impostor character took over TikTok, Twitter and Reddit. The word quickly moved from gaming to everyday conversation, school hallways and family group chats.

Parents’ guide to sus
If your child says something is sus, they usually mean it looks suspicious or strange. It is not rude in most cases. You can even use it to encourage safe behavior online: if a message, website or stranger seems sus, they should tell you before responding.
Sus in memes and internet culture
After Among Us became popular, sus took on a life of its own in memes. The red crewmate became a symbol of suspicion, and people added the little impostor figure to everyday photos of things that looked vaguely like it, such as a red bean or a fire hydrant, with the caption sus. The word sussy and phrases like when the impostor is sus turned into running jokes. Even people who never played the game began using sus because the memes were everywhere.

It also gives people a light way to raise concerns without sounding too accusatory, because it often comes across as playful.
Is sus still popular?
The peak Among Us craze has passed, but sus has stayed in everyday vocabulary. It is now simply a common way to say suspicious, used by teens, adults, gamers and non-gamers alike. Unlike many slang words that fade after a year, sus has lasted because it fills a real need: a quick, casual way to say something seems off. Expect to keep hearing it in group chats, comments and classrooms for years to come.
Final thoughts
