青春痘撞上你别逗
[qīng chūn dòu zhuàng shàng nĭ bié dòu]
This nickname translates literally to 'Pimples meet you, stop joking.' It could imply that dealing with teenage issues, especially appearance-related ones such as pimples, becomes particularly difficult or embarrassing in front of someone special, or it could simply suggest that pimples should not bother when encountering something beautiful.
