What does sus mean? The kids' slang, explained for parents

What does sus mean? "Sus" is short for "suspicious" or "suspect": something or someone seems shady or not quite right. The word is decades old in British and police slang, but kids picked it up from the game Among Us, where players vote on who's "sus." It isn't rude, though calling a person sus is a mild accusation.

Where sus comes from

"Sus" and "suss out" were British and police slang long before video games; in the UK, stop-and-search on suspicion under the Vagrancy Act 1824 was known as the "sus law." Kids picked up the word from the game Among Us, popular since 2020, where players meet to vote on who's acting suspicious.

Is sus a bad word?

Short answer: No. It contains no profanity. Calling a person "sus" is a mild accusation, so it can sting.

The habit kids may copy: blame first, proof later

In Among Us, you accuse, argue, and vote someone out. Some kids bring that home: "You're sus!" about a missing cookie, before anyone knows what happened.

Try tonight: did you see it?

When someone gets blamed, ask: "Did you see it, or are you guessing?" In our program, this is the lesson "Wisdom": thinking before deciding.
