平胸女屌小男
[píng xiōng nǚ diăo xiăo nán]
The term '平胸女屌小男', which may sound quite provocative or even impolite to some degree because of the word 屌(diào) used in it, could roughly mean a flat-chested girl playing hard to get or being arrogant toward small-dicked boys in slang language, expressing sarcasm towards appearance or character.
