Meaning

A lazy, drawn-out abbreviation of おかえり meaning 'welcome back' — used in chat and texting.

おかー is an ultra-casual shortening of おかえり (welcome back) with an elongated vowel. It is used in online chats, LINE groups, and gaming when someone returns after being away. The elongation gives it a relaxed, almost yawning quality. Like other abbreviated greetings (おは, おひさ), it signals closeness and comfort with the other person.
