"Awa' an bile yer heid"
This Scottish phrase is another one that needs a double-dose of translating! Simply putting it into English results in "Away and boil your head!" - which probably won't help you much.
What it means is something along the lines of 'Get lost!' or 'Forget it!' - and it's usually said to someone who is deemed to be talking rubbish, or wasting your time.
To be told to "Bile yer Heid" or Boil Your head, is to be told not to be so ridiculous or to be so absurd. Can also be used as a term of exclamation if someone is doing something stupid and its annoying to you. It is a common phrase in old scots but is still used today.
