菇凉我就是大大咧咧
[gū liáng wŏ jiù shì dà dà liĕ liĕ]
'Gu Liang' is the transliteration of girls in Chinese, hence this phrase literally says, 'Girl, I'm just casual.' A 'big big carefree' girl indicates that the person has a free-wheeling character and doesn't pay much attention to trivial matters; they have an easy-going and straightforward attitude towards life and don't dwell much on tiny details or overly worry about others’ perceptions of her behaviors.
