Translation: You're Crazy Anyone who is off their heads are basically mental. For example, if a Scot explained that they didn't like the sweet, sweet taste of Irn Bru, then the natural response would be 'yer aff yer heid.' This can also be applied to those who don't like whiskey, shortbread or haggis. Yes, these are typical stereotypes. Although people who genuinely enjoy haggis are most definitely 'aff yer heids', no thank you, please.
