If you text or scroll through TikTok, Instagram, or Snapchat, you’ve probably seen the term “HMU.” It pops up in messages, captions, and comments all the time. Like many online abbreviations, it saves time and sounds casual. People use it when they want someone to reach out or start a chat.

Even though it looks simple, “HMU” can have a few different tones — friendly, social, or even a little flirty. Let’s break down what it means and how people use it.

What Does “HMU” Mean?

“HMU” stands for Hit Me Up. It’s another way of saying “contact me,” “text me,” or “message me.” It’s used when someone wants you to get in touch later.

Example:

• “Going to the park later — HMU if you’re free.”
• “Need to talk about something, HMU.”

It’s short, casual, and perfect for friends, classmates, or anyone you talk to often online.

Where “HMU” Came From

The phrase “hit me up” has been around in spoken English for years. It means “reach out to me” or “get in touch.” The short form “HMU” started showing up online around 2009 on Urban Dictionary.

By the early 2010s, it became common on Facebook and Snapchat, where people used it in posts or bios like “HMU if you want to hang out.” Since then, it’s stayed popular as part of online slang used by teens, Gen Z, and young adults.

How “HMU” Is Used in Text Messages

In texting, “HMU” works as a quick, friendly request. It’s used to keep a conversation going or plan something later.

Examples:

• “HMU when you get home.”
• “I’m bored, HMU.”
• “Let’s hang this weekend. HMU!”

It replaces longer phrases like “message me later” or “send me a text.” It’s informal, so it fits best in friendly chats — not in professional messages or emails.
