In informal digital communication, HBU stands for "How about you?" It is a common shorthand used in texting, instant messaging, and social media. The acronym functions as a reciprocal question posed back to the conversation partner, especially after responding to a question.
Meaning and Usage
HBU directly asks the other person for their response, opinion, or situation concerning a topic previously mentioned. It fosters conversational reciprocity.
- Used as a follow-up to your own answer: Replying with HBU mirrors the initial question back to the sender.
- Common after answers about feelings ("I'm good, HBU?"), status ("Just got home, HBU?"), or opinions ("I liked the movie, HBU?").
Context is Key
Understanding HBU relies heavily on the conversation flow:

- Person A: "Hey, how are you doing?"
- Person B: "Pretty tired today. HBU?" (Meaning: "How about you? How are you doing?")
Common Variants
- WBU: "What about you?" (Often interchangeable with HBU).
- HBY: Less common alternative spelling for "How 'bout you?"
Key Points
- It's an abbreviation, not a standalone greeting. Use it within an existing exchange.
- Primarily used in casual digital conversations. Avoid it in formal writing.
- Don't confuse it with academic acronyms (e.g., Harvard Business Unit, Houston Baptist University). The texting context signals its meaning.
