意味

A super-short texting abbreviation of おはよう, meaning 'morning' or 'mornin'' — the laziest possible good morning.

おは is おはよう stripped down to its bare minimum — just two syllables fired off in a text or chat. It is the quintessential morning greeting for people too sleepy or too busy to type the full word. It is most common in LINE messages, Twitter/X posts, and group chats. Despite its extreme brevity, it carries warmth because its casualness implies closeness with the recipient.
