你那么放荡你爸妈知道吗
[nĭ nèi me fàng dàng nĭ bà mā zhī dào ma]
Literal translation 'Are your parents aware you are so reckless/uninhibited?' hints a teasing, reproving tone suggesting shock or disapproval at somebody's bold, perhaps outrageous behavior—it might also imply concern mixed with surprise at actions defying conventional norms.
