女人看不透因为胸前肉厚
[nǚ rén kàn bù tòu yīn wéi xiōng qián ròu hòu]
This is a rather vulgar and sexist username implying that women are hard to understand because of physical attributes. It reflects the idea, often present in internet slang, that men stereotype women based on physical appearances. Note: This type of language is not recommended as it objectifies people.
