我咋不发光了忘记交电费了
[wŏ ză bù fā guāng le wàng jì jiāo diàn fèi le]
This username humorously conveys a situation where the person is wondering why they aren't glowing anymore, and then realizes it's because they forgot to pay the electricity bill. It's often used as a light-hearted way to poke fun at oneself for not taking care of responsibilities or basic tasks.
