Gorblimey

Gorblimey: "God bless me!" An exclamation or adjective of emphasis. A "Gorblimey" was the common colloquial term for an unwired, floppy, field-service cap worn by a certain type of subaltern in defiance of the Dress Regulations. Lines from a song, popular before the war, ran:
 * My Old Man's a fireman, An' wot d'yer think o' that, He wears Gorblimey trousers An' a little Gorblimey 'at.
