老子我身穿校服拽天下菇凉我身穿校服倾天下
[lăo zi wŏ shēn chuān xiào fú zhuài tiān xià gū liáng wŏ shēn chuān xiào fú qīng tiān xià]
This phrase expresses confidence and charm while wearing school uniforms. 'Zhuai (拽)' implies cool or handsome, and 'Gula (菇凉, 姑娘 in formal writing)' means young girls. It humorously claims an irresistibly charming aura around the person wearing a uniform, which might attract everyone, both guys and girls.
