屌丝不是爷的范er剩女不是姐的范er
[diăo sī bù shì yé de fàn er shèng nǚ bù shì jiĕ de fàn er]
Roughly translates as 'Being an outcast (commoner) doesn’t make one a nobleman, being left over doesn't fit sister’s image’. Here, 'diao si' refers to an unsuccessful male individual and 'sheng nu' an unwed woman of considerable age; both are terms implying societal pressures.
