菇凉我品德高尚优雅大方
[gū liáng wŏ pĭn dé gāo shàng yōu yă dà fāng]
'Miss mushroom I am high-moral upright graceful'. This is often used playfully or ironically. The character 菇凉 is a pun on girls (姑娘). So, the person claims high virtue but in an odd, light-hearted way that doesn't take itself too seriously.
