骚乃人之本性
[sāo năi rén zhī bĕn xìng]
The user believes promiscuity or frivolity is inherent in human nature, which can be a challenging claim against traditional moral values and beliefs about goodness, purity, etc. In China, the word '骚' (sāo) could be interpreted as flirtatiousness, restlessness or agitation, which conveys rather pejorative meanings especially for women.
