我后桌的前桌最美最漂亮
[wŏ hòu zhuō de qián zhuō zuì mĕi zuì piāo liàng]
It translates into 'My seatmate behind and in front of me is the most beautiful and prettiest'. This indicates either genuine praise for two people sitting adjacent by the author or a way for the user to highlight their surrounding beauty environment. The term is casual and likely comes from a positive school memory.
