忘东忘西忘不了你丢三丢四丢不了你
[wàng dōng wàng xī wàng bù le nĭ diū sān diū sì diū bù le nĭ]
Translating this literally means 'I forget everything but I cannot forget you; I lose everything but I won't lose you.' The net name conveys strong affection for someone, expressing that they can be scatterbrained or absent-minded with almost anything else, but never when it comes to this special person.
