おやすー
Meaning: A casual, abbreviated way to say goodnight, shortened from おやすみ.
おやすー chops おやすみ even further and adds the elongation mark ー for a sleepy, relaxed feel. It is commonly used in late-night LINE chats and social media posts before bed. The tone is warm and intimate, typically used between close friends or romantic partners.
