Updated on

You’ve received a text from your kid with the letters SUS, and you aren’t sure what to make of it. SUS is an abbreviation often used in texting and online messaging.

What does SUS mean?

“SUS” is an abbreviation or slang for the word “suspicious” and it is often used when the texter wants to convey that something is suspicious or questionable.

SUS is used to shorten text messages, or tweets on the social media platform Twitter. It has become so popular in recent years, however, that many people say something is “sus” in social situations in place of the full word.

How to use SUS

  • “Don’t eat that, it looks SUS.”
  • “She seems a little SUS.”
  • “You are being totally SUS right now.”
  • “Everything he does is a little sus.”
  • SUS can be used in placement of the word suspicious in almost any sentence.

Using SUS the right way

As far as abbreviations go, there aren’t many rules for using SUS and the situations you choose to use it in can be any situation where you are suspicious of a person, place, or thing and don’t want to type out the full word.

SUS Variations

There are no variations of the word SUS as it is already a short version of the word suspicious, which isn’t very long.

There is, however, a term in British English used to describe a law where people could be arrested based on suspicion alone. It is known as the sus law short for suspicion law and it is only used in the UK.

Should you worry about your child using SUS?

SUS is a harmless texting term, and it is unlikely your child will get into trouble or say something bad while using it.

You may want to let your child know, however, that it is not to be used in professional situations and should only be used among friends and family.
