What Does "Sup" Mean in Texting?

Short answer: "Sup" is short for "What's up?" — a casual greeting asking what you've been doing or how you're doing. That's it. Nothing complicated here.

It's one of the most common text greetings you'll encounter, especially in casual conversations with friends, family, or people you know well. If someone texts you "Sup," they're not starting a formal correspondence.

Quick "How To" Guide

Using "Sup" in Texting

  1. Know your audience — Friends and close acquaintances only
  2. Keep it lowercase — "Sup" not "SUP" (all caps reads as shouting)
  3. Don't overdo it — Using "Sup" every single time you text someone gets old
  4. Add context if needed — "Sup, are you free tomorrow?" works better than just "Sup"
  5. Read the room — If someone always texts formally, don't force "Sup" on them

The Bottom Line

"Sup" is a greeting. A casual, efficient, lowercase greeting. Use it with people you're comfortable with. Don't use it professionally. That's the whole article.

If someone texts you "Sup" and you didn't expect it, just respond. No need to overthink it.
