我就是数学不好你咬我啊
[wŏ jiù shì shù xué bù hăo nĭ yăo wŏ a]
Expresses defiance and carelessness towards criticism of not being good at mathematics. The tone here is humorous, almost cheeky. Direct translation would be 'I'm just not good at math, what are you going to do about it? bite me?' Here biting someone doesn't really mean eating him up, but rather stands for taking actions against others.
