Acronym.
Short for "hit me up", a phrase from hip-hop and street slang, HMU spread with text messaging and early social networks like MySpace in the 2000s and has been standard in DMs and captions since.
HMU invites someone to get in touch: to make plans, ask a question or start a chat. It shows up in DMs, stories and captions ("HMU for collabs"). The tone is friendly and casual, and it works best when the next step is obvious, like a DM or a link. In more formal settings it can read as flippant.
HMU is widely understood in informal contexts, but its casual nature means it should be used carefully by brands. Ensure the tone aligns with your brand's voice and the context is clearly an invitation for contact, rather than a demand. Avoid in formal communications.
