RAF Banter - Lesson 1 with Squadron Leader Biggles
"Top hole. Bally Jerry pranged his kite right in the how's-your-father. Hairy blighter, dicky-birdied, feathered back on his Sammy, took a waspy,
flipped over on his Betty Harper's and caught his can in the Bertie."
Meanings:
Bally = intensifier
Jerry = German
Pranged his kite = crashed his plane
How's your father = Casual sex
Hairy blighter = Reference to caveman like hair translating to stupid person
Dicky birdied = Dicky = injured, so reference to aerial manoeuvre that looks
like an injured bird; probably a corkscrew
Feathered back on his Sammy = slowed down his engine
Took a waspy = got shot (stung)
Flipped over on his Betty Harper's = turned upside-down
Caught his can in the Bertie = Plane sunk in the sea
