失去蜡笔的小新
[shī qù là bĭ de xiăo xīn]
'Crayon-less Crayon Shin-chan,' a twist of a character's name from the famous Japanese anime Crayon Shin-chan. Here, the owner suggests they’ve somehow ‘lost’ an important attribute, similar to Shin-chan without his crayons. This can indicate feeling incomplete or lost like losing some essential items or features that define themselves.
