长得帅不是我的错漂亮不是我的罪过
[zhăng dé shuài bù shì wŏ de cuò piāo liàng bù shì wŏ de zuì guò]
'Being handsome isn’t my fault. Being beautiful isn't a crime,' which could mean this username declares one’s own good physical appearance boldly and humorously. Also, there might be an underlying implication about being misjudged or disliked purely based on looks.
