西瓜说她是夏天他媳妇夏天说他是西瓜她爷们
[xī guā shuō tā shì xià tiān tā xí fù xià tiān shuō tā shì xī guā tā yé men]
A rather amusing and convoluted expression that roughly translates to 'Watermelon says she is Summer's wife; Summer says he is Watermelon's man.' This could imply a close and reciprocal relationship or play on words between two people named 'Watermelon' and 'Summer'. In Chinese culture, it also conveys a playful and teasing nature between friends or lovers using personified terms.
