快看我发光了耶别闹交出荧光棒
[kuài kàn wŏ fā guāng le yē bié nào jiāo chū yíng guāng bàng]
'Look, I’m glowing! Stop kidding, hand over the glow stick' is likely referring to the excitement one gets from attention and admiration. It might describe an amusing or celebratory scenario, where someone wants others to join and appreciate them.
