“SUS” – “Something’s Suspicious” 🕵️‍♂️

If you scroll TikTok, or any other social media, you’ll see sus everywhere. For English learners, mastering this short, punchy slang will boost your listening skills and make your chats feel instantly up-to-date. Let’s unpack its meaning, origin, and the best ways to drop it in real conversation, so you never miss a “sus” moment again.


What does sus mean? 🤔

Sus (pronounced /sʌs/) is the short form of suspicious or suspect. Use it when someone’s story sounds shady, an alibi doesn’t add up, or a situation feels off.

Friend: “I found a brand-new iPhone for $20.”
You: “Hmm… that’s sus.”


Where did sus come from? 📜

  • Early roots: Police shorthand in the 20th century shortened suspect to sus.

  • Today: Gen Z uses sus in texts, memes, and even casual work chats to label anything questionable.
