Below, you’ll find more than 900 words filled with smart, friendly, flirty, and funny ways to respond, along with tips for picking the right reply every time.

Understanding What “What’s Up?” Really Means

Before deciding how to reply, it helps to understand what “What’s up?” actually means.

Most of the time, it’s not a literal question. People rarely expect you to explain everything happening in your life. Instead, “What’s up?” is usually:

• a casual greeting
• a conversation starter
• a quick way to check in
• a way to show friendliness or interest
• filler that replaces “hello”

Because it’s such a flexible phrase, your reply can also be flexible. You can keep things short, open the door to more conversation, or turn it into something more fun.

The key is matching the tone to the relationship — and your own personality.

Simple and Casual Replies

Sometimes, you just need a natural answer that keeps the chat flowing without too much effort. Here are some easy options:

• “Not much, how about you?”
• “Just relaxing. You?”
• “Hey! Just hanging out. What’s up with you?”
• “All good here — you?”
• “Nothing crazy. What’s going on?”
• “Just chilling. What’s up on your end?”

These responses work for almost anyone — friends, coworkers, acquaintances, or someone you just started texting. They keep things open-ended without oversharing.

Friendly Replies That Keep the Conversation Going

If you want to sound warm and engaged, try replies that invite more conversation. These work great with friends, family, or someone you like talking to:

• “Just finishing up my day. What about you?”
• “Trying to be productive! How’s your day going?”
• “Thinking about dinner — what are you up to?”
• “Just doing a few things. Tell me something interesting!”
• “Not much, but I’m happy to hear from you. What’s new?”

These show that you’re open to chatting and that you actually care about their response.

Funny Replies to Make Them Smile

Sometimes humor is the perfect way to break the ice, lighten the mood, or show off your personality. Try one of these playful replies:

• “The sky. Always the sky.”
• “Just trying to figure out why I’m still awake.”
• “Probably something I shouldn’t be doing.”
• “Same thing that was up last time you asked.”
• “My blood pressure… but it’s fine now.”
• “Living the dream. It’s a weird dream, but still.”
• “Waiting for you to say something interesting.”

These kinds of responses work especially well with friends or someone who appreciates your sense of humor.

Professional replies avoid being too casual while still maintaining a friendly tone.

How to Reply When You Don’t Want to Chat
