桃花侠大战菊花怪
[táo huā xiá dà zhàn jú huā guài]
It's like saying 'Plum blossom warrior battles against chrysanthemum monster'. This kind of nickname has elements from Chinese literature or fantasy tales where plum blossoms represent nobility and elegance and chrysanthemums stand for tenacity and endurance. But here these classic flower-related metaphors are applied in funny scenarios creating humor or parody effect in the modern setting of the net world.
