Here is a fun slang saying in Chinese that is the equivalent of the English saying ‘on your bike’, which means ‘get out of here’, or ‘no chance’.

The literal translation of the phrase is ‘go and hit a wall’ as in ‘run into a wall’, and means something more like “you may as well go and run into the wall, because there’s no way that’s going to happen”. It also seems very similar to the American saying “go jump off a cliff” (American’s please correct me here if there is a better equivalent US English saying).
The usage of this saying could go something like this:
Person A: 借我$500塊（借我$500块 jiè wǒ $500 kuài）
Person B: 去撞牆，你還欠我$100塊（去撞墙，你还欠我$100块 qù zhuàng qiáng, nǐ hái qiàn wǒ $100 kuài）
The English translation being:
Person A: Lend me $500
Person B: No chance, you still owe me $100
substitute ‘no chance’ for the term of your choice: piss off; do one; whatever, etc.
