耶嘿你会发光哎废话我有荧光棒
[yē hēi nĭ huì fā guāng āi fèi huà wŏ yŏu yíng guāng bàng]
'Yes! You shine brightly - duh, I have a glow stick!' - This is likely meant as playful banter between friends, where one acknowledges another for standing out in some way (shining bright), while jokingly pointing out why that's happening because they're holding a glowing stick. 'Yayha' ('耶嘿') and 'eh-waste-word' ('哎废话') both act like conversational particles in Chinese, which do not translate directly to English.
