Chutiya vs Dhakkan

So at a party last evening, I quoted Hanlon’s Razor to somebody:

Never attribute to malice that which is adequately explained by stupidity.

‘Say it in Hindi, say it in Hindi,’ my hosts implored. ‘Tu angrezi mein bahut bak-bak karta hai!

So this is what I came up with:

Tum yeh na samjho ki woh chutiya hai. Woh sirf dhakkan hai!

I have to now admit that it sounds much better in Hindi.
