In Hindi, the word फेंकना (fenkna) describe an act of boasting in a way that is obviously untrue and ridiculous. It might be me bragging about swimming twenty miles few years ago. If you know me, and the fact that I lack any athletic experience, it would be easy to infer that the claim is plain absurd.
The word literally means "to throw", but its use that way is quite popular.
The closest word that comes to mind is "bullshiting", but I wanted to know if there's a more formal one to describe this action.
