一刀斩的你桃花开
[yī dāo zhăn de nĭ táo huā kāi]
In literal translation: With one slash I made your peach blossoms bloom. In essence, the person who chooses this nickname possibly believes they play an important role in bringing happiness (or romance) to others like making them encounter wonderful loves ('Peach blossom' in China represents flourishing romantic encounters). The 'one slash' metaphorically signifies sudden impact on the positive change of luck or fortune in another person’s affairs especially romantically.
