What is Blimy?
Posible Euphemism for "Blind me" often used with 'Gowd' as "Gowd blimy" - obviously for "God blind me!" Probably derived from such remarks as "God blind me if I ever see anything more beautiful." But now use as an expression of shock of any sort.
Blimy, what a beauty!
Gowd blimy! What a motor!
See blow me, jeez
