**Short answer:** Sup means "what's up?". It is a quick, casual hello, like "hey, how's it going?". From a crush, it shows they wanted to talk to you, but it puts the work on you. What they do after your reply shows how much they really care.

## What does sup mean?

Sup is short for "what's up", written the way people say it fast. You will also see **wassup**, **wsup** and **'sup**. It can mean:

- "hello"
- "how are you?"
- "what are you doing right now?"

Most people do not expect a big answer. "nm, you?" ("not much, you?") is the classic reply.

## What does sup mean from a guy?

From a guy, "sup" is one of the most common openers. It is easy and low-risk: he can talk to you without needing a reason. It does not prove a crush, but it does mean you came to mind.

If he answers your reply with questions, jokes or a plan, he wants a real chat. If he sends "sup", you answer, and he replies "cool", it was probably boredom. Our guide on how to [keep a conversation going over text](https://thecringe.app/blog/keep-a-conversation-going-over-text) has ideas for turning a "sup" into more.

## What does sup mean from a girl?

From a girl, "sup" can feel a bit more direct. Many people wait for the other person to text first. If she opens with "sup" or "supp 😊", she chose to start the chat. That is a small, good sign.

## Is sup a good sign?

It is neutral. It is better than silence, but it is also low effort. Check the context:

- **Warm:** "sup stranger 🙂" after a few quiet days. They missed you a bit.
- **Filler:** "sup" every day with no follow-up. A habit, not a plan.
- **Late night:** "sup" at 1am, with nothing during the day, can work like a "u up" text.

"Sup" is close to [WSG](https://thecringe.app/meaning/wsg) and [WYD](https://thecringe.app/meaning/wyd), which also open a chat without a topic.

## How to reply to sup

**Flirty:**

- "just thinking about you, weirdly 😏"
- "nothing until you texted"

**Friendly:**

- "nm, just got back from the gym. you?"
- "chilling and avoiding homework lol. what's up with you?"

**Busy:**

- "at work rn, talk later?"

**Not interested:**

- "nm"
- "not much"

Tip: give one real detail and ask one question back. That makes it easy to keep talking.
