没交电费瞎发啥光没事我帮你交电费
[méi jiāo diàn fèi xiā fā shá guāng méi shì wŏ bāng nĭ jiāo diàn fèi]
If You Haven't Paid the Electricity Bill, Why Do You Emit Light? I'll Pay Your Electricity Bill if Necessary. In fact, this is an expression showing care for others through humor, especially friends who waste electricity unconsciously.
