You are late. You are in a taxi, and you'd like to ask the driver to hurry it up. To say that, you say 快点 [=kuai4 dian3 = fast little = hurry it up]. If if you live in Beijing, you add an "rrrrrr" to this by adding a 儿, so it would be 快点儿. No the 儿 doesn't mean anything, it's just a sound we like in Beijing.
Next, you need to know how to say "otherwise". (It's very hard to threaten someone without knowing how to say "otherwise".) In Mandarin, you can say 要不然 = yao4 bu0 ran2 = otherwise.
Of course, to say "I will bite you to death" you simply say 我咬死你 = wo3 yao3 si3 ni3 = I bite death you.
So, to speed up that cab, just say 快点儿要不然我咬死你 =kuai4 dianr3 yao4 bu0 ran2 wo3 yao3 si3 ni3 = hurry little otherwise I bite death you = hurry up or I am going to bite you to death.
Use wisely, and happy biting.
