再惹我我就给你唱小苹果

This internet handle playfully conveys a teasing warning to someone. 'Little Apple' refers to a very popular but somewhat cheesy Chinese song. The phrase is light-hearted, implying 'If you bother me again, I will do something annoying back to you,' showcasing an attitude of lightheartedness mixed with a small hint of threat.
