妈妈说坏女孩最可爱了
[mā mā shuō huài nǚ hái zuì kĕ ài le]
'Mom Said Naughtiest Girls Are Most Cute.' Perhaps influenced by certain cultural ideas, the creator of this name wants to break conventional beliefs and express self-admiration with irony, implying girls shouldn't adhere too much to being 'good', but instead, showing off more personality or character might be lovelier.
