Hi

Dears

1) Is this idiom common? => "talk the hind leg off a donkey"

2) I heard this term "Tommy talks" and I am not sure if it’s correct please help me(let me know any term close to)

Thanks

I've never heard number 2, but I've heard number 1 and dozens of variations of it.

In BrE we have 'Tommy rot' for when someone is talking nonsense.
