女生都装纯男生都装逼
[nǚ shēng dōu zhuāng chún nán shēng dōu zhuāng bī]
A rather cynical view expressing the notion that in social settings, many girls pretend to be innocent while boys try too hard to impress, often showing off unnaturally. The term '装' can imply pretension or artificiality in demeanor or behavior.
