A word many won't have heard since they were in nursery school.
However, in backward parts of the UK, there was once an Escort Cosworth which was registered with a numberplate which ended in these three letters... therefore, completely rationally, the car which had this numberplate was referred to as YUM, by fully grown adults.
Awiiiite guvnor, apples n pears, turkish baaf... 'ow did YUM get on at Brunters?
Mate, can't adam'n'eve it, YUM never 'it 200mph today either boss... and when me old china parked up... we saw a small elderly gent chuckle before he was driven away in his big boostin white Saph Cossie? Ye get me?
