rehi

Internet slang shorthand for 'hello again,' used when someone returns to a chat room, forum, or messaging thread after a brief absence. Common in early IRC (Internet Relay Chat) culture and still seen in some Discord servers or online communities today. The 're-' prefix signals a return rather than a first greeting — it's efficient, friendly, and signals awareness of the ongoing conversation. Tone is typically casual and warm, not formal in any way.
