卖萌光荣卖萌可耻

This username combines contrasting views on the action of 'acting cute' or 'cute gestures'. In Chinese internet culture, "acting cute" (卖萌) is a behavior where someone, often in a playful and innocent way, acts younger or more childlike to gain attention or affection. Here, by combining both 'glory' (光荣) and 'shame' (可耻) with it, the username reflects a humorous view toward this phenomenon.
