When I was about 6 my mum always used to talk about tatty ard sheep or so I thought, until I pointed out some tatty ard sheep one day whilst out for a drive in the car, my dad had to pull the car over he was laughing so much apparently my mum actually called them tatty arsed sheep and I'd just misheard her.
